(a) How many of the bag's black marbles were chosen?

(b) How many of the bag's red marbles were not chosen?

(c) How many of the bag's black marbles were not chosen?

After using **concept of proportions**, 20 of the bag's black marbles were chosen, 10 of the bag's red marbles were not chosen and 4 of the bag's black marbles were not chosen.

To answer the questions using the given information, we can use the concept of proportions. The formula we can use is:

Part/Whole = Fraction/Total

(a) To find the number of black marbles chosen, we need to calculate 5/6 of the total black marbles in the bag. Given that there are 24 black marbles in the bag, we can calculate:

Number of **black** marbles chosen = (5/6) * 24 = 20

Therefore, 20 of the bag's black marbles were chosen.

(b) To find the number of red marbles not chosen, we first need to determine the total number of red marbles in the bag. We know that there are 34 marbles in total and 24 of them are black. Therefore, the number of red marbles can be calculated as:

Number of red marbles = Total marbles - Number of black marbles = 34 - 24 = 10

Since all the black marbles were chosen (as calculated in part (a)), the number of red **marbles** not chosen would be the remaining red marbles. Therefore, 10 of the bag's red marbles were not chosen.

(c) To find the number of black marbles not chosen, we can subtract the number of black marbles chosen (as calculated in part (a)) from the total number of black marbles in the bag:

Number of black marbles not chosen = Total black marbles - Number of black marbles chosen = 24 - 20 = 4

Therefore, 4 of the **bag's** black marbles were not chosen.

The correct answer is: The columns do not span R* because the reduced row echelon form of the** augmented matrix** is 1 0 -1 0 0 1 -2 0 0 0 0 0which does not have a pivot in every row.

We need to determine the rank of the matrix A and compare it with the dimension of R₃.

Let's begin by setting up the augmented matrix [A|0] and reducing it to **row-echelon** form: RREF([A|0]) = 1 0 -1 0 0 1 -2 0 0 0 0 0

We see that the third column of the matrix does not have a pivot element in the row-echelon form, which means that the corresponding variable (x₃) is a free variable.

This in turn implies that the system of **linear equations** Ax = 0 has non-trivial solutions (that is, solutions other than x = 0), and hence the rank of A is less than 3.

Since the rank of A is less than the dimension of R₃, we can conclude that the columns of A do not span R₃.

Therefore, the correct answer is: The columns do not span R* because the **reduced row** echelon form of the augmented matrix is 1 0 -1 0 0 1 -2 0 0 0 0 0which does not have a pivot in every row.

Evaluate the integral π/4∫0 7^cos 21 sin2t sin2t dt.

The value of the **integral **π/4∫0 7^cos 21 sin^2t sin^2t dt is approximately 0.229.

To evaluate the integral, we can start by simplifying the expression within the integral. By applying the **trigonometric **identity sin^2θ = (1 - cos(2θ))/2, we can rewrite the **integral **as follows:

π/4∫0 7^cos 21 sin^2t sin^2t dt = π/4∫0 7^cos 21 (1 - cos(2t))/2 * (1 - cos(2t))/2 dt.

Next, we expand and simplify the expression:

= π/4∫0 7^cos 21 (1 - 2cos(2t) + cos^2(2t))/4 dt

= π/4∫0 (7^cos 21 - 2(7^cos 21)cos(2t) + (7^cos 21)cos^2(2t))/4 dt

= (π/16)∫0 7^cos 21 dt - (π/8)∫0 (7^cos 21)cos(2t) dt + (π/16)∫0 (7^cos 21)cos^2(2t) dt.

The first integral, (π/16)∫0 7^cos 21 dt, can be directly evaluated, resulting in a constant value.

The second integral, (π/8)∫0 (7^cos 21)cos(2t) dt, involves the product of a constant and a trigonometric **function**. This can be integrated by using the substitution method.

The third **integral**, (π/16)∫0 (7^cos 21)cos^2(2t) dt, also requires the use of trigonometric **identities **and substitution.

After evaluating all three integrals, their respective values can be added together to obtain the final result, which is approximately 0.229.

Assume that you have a sample of size 10 produces a standard deviation of 3, selected from a normal distribution with mean of 4. Find c such that P (x-4)√10 3 C = 0.99.

If we have a sample of size 10 produces a **standard deviation** of 3, selected from a normal distribution with a mean of 4. The value of c such that P(x < c) = 0.99 is approximately equal to 6.20.

The standard deviation (σ) of a sample of size n=10, is 3, and the mean (μ) of the **population **is 4. The probability of x < c = 0.99. We need to find the value of c. We know that the sample mean (x) follows the normal distribution with mean (μ) and standard deviation (σ/√n).

Hence, the standard error (SE) of the sample mean is given by;

SE = σ/√nSE = 3/√10 = 0.9487

The z-score for a confidence level of 99% (α = 0.01) is 2.33 from the standard normal distribution table. By substituting the values in the formula for the **z-score**;

z = (x - μ) / SE2.33 = (c - 4) / 0.9487

Solving for c;c - 4 = 2.33 x 0.9487c - 4 = 2.2047c = 6.2047c ≈ 6.20

7. For the function y=-2x³-6x², use the second derivative tests to: (a) determine the intervals which are concave up or concave down. (b) determine the points of inflection. (c) sketch the graph with the above information indicated on the graph.

Using the second **derivative** tests, we can determine the intervals of concavity for the function y = -2x³ - 6x² and find the points of **inflection**. We can then sketch the graph with this information.

To determine the intervals of **concavity**, we need to find the second derivative of the function. Let's start by finding the first **derivative** of y = -2x³ - 6x².

The first derivative is dy/dx = -6x² - 12x. To find the second derivative, we **differentiate** the first derivative with respect to x.

Taking the derivative of the first derivative, we get d²y/dx² = -12x - 12.

To find the intervals of concavity, we need to determine where the second derivative is positive (concave up) or negative (concave down).

Setting -12x - 12 equal to zero and solving for x, we find x = -1.

By choosing test points within intervals on either side of x = -1, we can determine the concavity of the function. For example, if we plug in x = -2 into the second derivative, we get a positive value, indicating concave up. Similarly, if we plug in x = 0, we get a **negative** value, indicating concave down.

Next, to find the points of inflection, we set the second derivative equal to zero and solve for x.

-12x - 12 = 0

-12x = 12

x = -1

So, x = -1 is a potential point of inflection. To confirm if it is a point of inflection, we can check the concavity of the function around this point.

Finally, armed with the intervals of concavity and the points of inflection, we can sketch the graph of y = -2x³ - 6x², indicating the concave up and concave down intervals and the point of inflection at x = -1.

The manufacturer of a new chewing gum claims that 80% of dentists surveyed prefer their type of gum and recommend it for their patients who chew gum. An independent consumer research firm decides to test their claim. The findings in a sample of 200 dentists indicate that 74.1% of the respondents do actually prefer their gum. State the null and alternative hypotheses, the test statistic and p-value to test the claim.

The** test statistic** is z = -2.09 and the **p-value** is approximately 0.037.

The **null and alternative hypotheses** for testing the claim can be stated as follows:

Null Hypothesis (H₀): The proportion of dentists who prefer the manufacturer's chewing gum and recommend it for their patients is equal to 80%.

Alternative Hypothesis (H₁): The proportion of dentists who prefer the manufacturer's chewing gum and recommend it for their patients is different from 80%.

In mathematical notation:

H₀: p = 0.80

H₁: p ≠ 0.80

where p represents the true proportion of dentists who prefer the manufacturer's chewing gum and recommend it for their patients.

To test the claim, we will conduct a hypothesis test using the sample data. The test statistic used in this case is the z-score, which measures how many standard deviations the sample proportion is away from the hypothesized proportion.

The formula for calculating the **z-score** is:

z = (p - p₀) / √((p₀ * (1 - p₀)) / n)

where p is the sample proportion, p₀ is the hypothesized proportion under the null hypothesis, and n is the sample size.

In this case, the sample proportion is p = 0.741 and the hypothesized proportion under the null hypothesis is p₀ = 0.80. The sample size is n = 200.

Calculating the z-score:

z = (0.741 - 0.80) / √((0.80 * (1 - 0.80)) / 200)

z = -2.09

For a two-tailed test (since the alternative hypothesis is "different from 80%"), the p-value is calculated as twice the probability of obtaining a z-score as extreme as the observed z-score (in either tail of the distribution).

(Type an exact answer, using r as needed.)

In each question, we are asked to find the surface area generated when a given curve is revolved about a **specific axis**. We need to evaluate the integral of the surface area formula and find the exact answer in terms of the given **variables**.

For the curve y = 5x + 7, revolved about the x-axis, we can use the formula for the surface area of revolution: **A = 2π ∫[a, b] f(x) √(1 + (f'(x))²) **dx, where [a, b] represents the interval of x-values. In this case, the interval is from 0 to 2. We substitute f(x) = 5x + 7 and find f'(x) = 5. Evaluating the integral gives us the** surface area** in square units.

For the curve y = 4v, revolved about the x-axis, we again use the surface area formula. However, the integration limits and the variable change to v instead of x. We substitute f(v) = 4v and f'(v) = 4 in the formula and integrate over the given interval to find the surface area.

For the curve y = 17, revolved about the x-axis, we have a horizontal line. The surface area formula is slightly different in this case. We use A = 2π ∫[a, b] y √(1 + (dx/dy)²) dy, where [a, b] represents the interval of y-values. Here, the interval is from **0 to 17**. We substitute y = 17 and dx/dy = 0 in the formula and integrate to find the surface area.

For the curve y = (3x)³, revolved about the y-axis, we need to rearrange the formula to be in terms of y. We have x = (y/3)^(1/3). Then, we use A = 2π ∫[a, b] x √(1 + (dy/dx)²) dx, where [a, b] represents the interval of y-values. In this case, the interval is from 0 to 3. We substitute x = (y/3)^(1/3) and dy/dx = (1/3)(y^(-2/3)) in the formula and** integrate** to find the surface area.

By applying the respective surface area formulas and performing the necessary integrations, we can determine the surface areas in square units for each given curve revolved about its specified axis.

The integral of arcsin(x) from 0 to 1 is π/6, and the **integral** of x√(1+3x) from 0 to 2 can be evaluated using **substitution** to find the value of 64/105.

1) To find the integral of arcsin(x) from 0 to 1, we can use integration techniques. We can apply **integration** by parts or integration by substitution. In this case, integration by substitution is a suitable method. Let u = arcsin(x), then du = 1/√(1-x²) dx. The integral becomes ∫du = u + C. Plugging in the limits of integration, we have ∫[arcsin(x) dx] from 0 to 1 = [arcsin(1)] - [arcsin(0)] = π/2 - 0 = π/6.

2) To evaluate the integral of x√(1+3x) from 0 to 2, we can use integration **techniques** such as u-substitution. Let u = 1+3x, then du = 3 dx. Rearranging the equation, we have dx = du/3. Substituting the values, the integral becomes ∫[x√(1+3x) dx] from 0 to 2 = ∫[(u-1)/3 √u du] from 1 to 7. Simplifying the **expression** and evaluating the integral, we get [(64/105)(√7) - 0] = 64/105.

Therefore, the integral of arcsin(x) from 0 to 1 is π/6, and the integral of x√(1+3x) from 0 to 2 is 64/105.

If the **volume **of the region bounded, then the value of a is **a⁴ - (2/3)a² + (1/5) - 16/π = 0.**

To find the volume of this region, we need to integrate the given **function **with respect to z over the region. Since the region extends indefinitely downwards, we will use the concept of a double integral to account for the entire region.

Let's denote the volume of the region as V. Then, we can express V as a double integral:

V = ∬[R] (a² - x² - y²) dz dA,

where [R] represents the region defined by the inequalities.

To simplify the calculation, let's transform the integral into cylindrical coordinates. In cylindrical **coordinates**, we have:

x = r cosθ,

y = r sinθ,

z = z.

The Jacobian determinant for the cylindrical coordinate transformation is r, so the integral becomes:

V = ∬[R] (a² - r²) r dz dr dθ.

Now, we need to determine the limits of integration for each variable. The region is bounded above by the surface z = a² - x² - y². Since this surface is defined as z = a² - r² in cylindrical coordinates, the upper limit for z is a² - r².

Finally, for the variable θ, we want to cover the entire region, so we integrate over the full range of θ, which is 0 to 2π.

With the limits of **integration **determined, we can now evaluate the integral:

V = ∫[0 to 2π] ∫[1 to ∞] ∫[0 to a²-r²] (a² - r²) r dz dr dθ.

Now, we can integrate the innermost integral with respect to z:

V = ∫[0 to 2π] ∫[1 to ∞] [(a² - r²)z] (a²-r²) dr dθ.

Simplifying the inner integral:

V = ∫[0 to 2π] [(a² - r²)(a² - r²)] dθ.

V = ∫[0 to 2π] (a⁴ - 2a²r² + r⁴) dθ.

We can now integrate the remaining terms with respect to r:

V = ∫[0 to 2π] [a⁴r - (2/3)a²r³ + (1/5)r⁵] dθ.

Next, we evaluate the inner integral:

V = [a⁴ - (2/3)a² + (1/5)] ∫[0 to 2π] dθ.

V = [a⁴ - (2/3)a² + (1/5)].

Since we integrate with respect to θ over the full **range**, the difference in θ between the limits is 2π:

V = [a⁴ - (2/3)a² + (1/5)] (2π).

Finally, we know that V is given as 32 units. Substituting this value:

32 = [a⁴ - (2/3)a² + (1/5)] (2π).

Solving for 'a' in this equation requires solving a quadratic equation in 'a²'. Let's rearrange the equation:

32/(2π) = a⁴ - (2/3)a² + (1/5).

16/π = a⁴ - (2/3)a² + (1/5).

We can rewrite the equation as:

a⁴ - (2/3)a² + (1/5) - 16/π = 0.

To determine the value of ϵ (**molar** absorptivity) at λmax (wavelength of maximum absorption) for the blue dye, we would need access to the specific data from the spectrometer simulation.

Without the actual values, it is not possible to provide an accurate answer.

The molar absorptivity (ϵ) is a constant that represents the ability of a substance to absorb light at a specific **wavelength**. It is typically given in units of L·mol−1·cm−1 or cm−1·μm−1.

To obtain the value of ϵ at λmax for the blue dye, you would need to refer to the absorption **spectrum** data obtained from the spectrometer simulation.

The absorption spectrum would provide the intensity of light absorbed at different wavelengths.

By examining the absorption **spectrum**, you can identify the wavelength (λmax) at which the blue dye exhibits maximum absorption. At this wavelength, you would find the corresponding absorbance value (A) from the spectrum.

The molar absorptivity (ϵ) at λmax can then be calculated using the **Beer-Lambert Law** equation:

ϵ = A / (c * l)

Where:

A is the absorbance at λmax,

c is the concentration of the blue dye in mol/L, and

Solve the equation f/3 plus 22 equals 17

The solution to the **equation **f/3 + 22 = 17 is f = -15.

Solve the equation f/3 + 22 = 17, we need to isolate the **variable **f on one side of the equation. Here's a step-by-step solution:

Let's start by **subtracting **22 from both sides of the equation to move the constant term to the right side:

f/3 + 22 - 22 = 17 - 22

f/3 = -5

Now, to eliminate the **fraction**, we can multiply both sides of the equation by 3. This will cancel out the denominator on the left side:

(f/3) × 3 = -5 × 3

10 Points: Q5) A company that manufactures laser printers for computers has monthly fixed Costs of $177,000 and variable costs of $650 per unit produced. The company sells the printers for $1250 per unit. How many printers must be sold each month for the company to break even?

To find the **break-even** point, we need to determine the number of **printers **that need to be sold each month. The company must sell approximately 295 printers each month to break even.

To break even, the company must sell enough laser printers to cover both fixed costs and **variable **costs. In this case, the company has fixed costs of $177,000 and variable costs of $650 per unit produced. The selling price per unit is $1250. To find the break-even point, we need to determine the number of printers that need to be **sold **each month.

Let's denote the number of printers to be sold each month as x. The total cost (TC) can be calculated as the sum of fixed costs (FC) and variable costs (VC) multiplied by the number of units produced (x):

TC = FC + VC * x

Substituting the given values, we have:

TC = $177,000 + $650x

The **revenue **(R) can be calculated by multiplying the selling price (SP) per unit by the number of units sold (x):

R = SP * x

Substituting the given selling price of $1250, we have:

R = $1250 * x

To break even, the revenue must cover the total cost:

R = TC

$1250 * x = $177,000 + $650x

Simplifying the **equation**, we can isolate x to find the break-even point:

$1250x - $650x = $177,000

$600x = $177,000

x = $177,000 / $600

x ≈ 295

Therefore, the company must sell approximately 295 printers each month to break even.

Which of the following functions have an average rate of change that is negative on the interval from x = -4 to x = -1? Select all that apply. f(x) = x² - 2x + 8 f(x) = x² - 8x + 2 ((x) = 2x² - 8 f(x) = -6 Submit

**Answer:** The given **functions** have an** average rate** of change that is negative on the interval from x = -4 to x = -1.

Thus, the correct option is:

Option A:

f(x) = x² - 2x + 8

**Step-by-step explanation:**

The given functions are as follows:

f(x) = x² - 2x + 8

f(x) = x² - 8x + 2

f(x) = 2x² - 8

f(x) = -6

To calculate the average rate of change (ARC) between two** points**, we have to use the following formula:

ARC = [f(b) - f(a)] / (b - a)

Where f(a) is the function** value** at a and f(b) is the function value at b, and a and b are the two given points.

Now, let's calculate the average rate of change of each function for the given **interval**:

a = -4 and b = -1

For

f(x) = x² - 2x + 8

ARC = [f(b) - f(a)] / (b - a)

ARC = [(-1)² - 2(-1) + 8 - [(-4)² - 2(-4) + 8]] / (-1 - (-4))

ARC = [1 + 2 + 8 - 16 + 8 - 2 + 16] / 3

ARC = 7 / 3

> 0

The average rate of change is positive, so

f(x) = x² - 2x + 8 does not have an average rate of change that is negative on the interval from x = -4 to x = -1.

For

f(x) = x² - 8x + 2

ARC = [f(b) - f(a)] / (b - a)

ARC = [(-1)² - 8(-1) + 2 - [(-4)² - 8(-4) + 2]] / (-1 - (-4))

ARC = [1 + 8 + 2 + 16 + 32 + 2] / 3

ARC = 61 / 3

> 0

The average rate of change is positive, so f(x) = x² - 8x + 2 does not have an average rate of change that is negative on the interval from x = -4 to x = -1.

For

f(x) = 2x² - 8

ARC = [f(b) - f(a)] / (b - a)

ARC = [2(-1)² - 8 - [2(-4)² - 8]] / (-1 - (-4))

ARC = [2 - 8 + 32 - 8] / 3

ARC = 18 / 3

= 6

> 0

The average rate of change is positive, so f(x) = 2x² - 8 does not have an average rate of change that is negative on the interval from x = -4 to x = -1.

For

f(x) = -6

ARC = [f(b) - f(a)] / (b - a)

ARC = [-6 - [-6]] / (-1 - (-4))

ARC = 0 / 3

= 0

The average rate of change is zero, so f(x) = -6 does not have an average rate of change that is negative on the interval from x = -4 to x = -1.

The value of k for which the **system** has **no solutions** is k = 20/3.

To determine the value of k for which the system has **no solutions**, we need to check for **consistency** of the **system of equations**.

This can be done by performing row operations on the **augmented matrix** of the system and analyzing the resulting row-echelon form.

The augmented **matrix** for the given system is:

[ 1 1 3 | 3 ]

[ 1 2 -4 | -3 ]

[ 7 17 k | -38 ]

Let's use **row operations** to simplify the matrix:

R2 = R2 - R1

R3 = R3 - 7R1

The **new matrix** becomes:

[ 1 1 3 | 3 ]

[ 0 1 -7 | -6 ]

[ 0 10 -21-k | -59 ]

Next, we'll perform **additional** row operations:

R3 = 10R3 - R2

The **matrix** now looks like this:

[ 1 1 3 | 3 ]

[ 0 1 -7 | -6 ]

[ 0 0 -21k+139 | -1 ]

Now, the **last row** can be written as -21k + 139 = -1.

Simplifying this equation, we have:

-21k + 139 = -1

To isolate k, we can **subtract** 139 from both sides:

-21k = -1 - 139

-21k = -140

Finally, **divide** both sides by -21 to solve for k:

k = (-140) / (-21)

k = 20/3

Therefore, the value of k for which the **system** has **no solutions** is k = 20/3.

Find the Maclaurin series representation for the following function f(x) = x² cos( 1/(3 ) x)"

The **Maclaurin series** representation for the function f(x) = x^2cos(1/3x) can be found by expanding the function as a **power series** centered at x = 0.

To find the Maclaurin series representation of f(x), we start by calculating the** derivatives **of f(x) with respect to x. Using the power series expansion of the **cosine function**, we can express cos(1/3x) as a series. Then, we multiply the resulting series by x^2. By combining the terms and simplifying, we obtain the Maclaurin series representation of f(x).

The Maclaurin series for f(x) = x^2cos(1/3x) is given by:

f(x) = x^2 - (1/9)x^4 + (1/3!)(1/81)x^6 - (1/5!)(1/729)x^8 + ...

(a) To prove the **product rule** for complex functions, we show that if f(z) and g(z) are analytic, then their product h(z) = f(z)g(z) is also analytic, and h'(z) = f'(z)g(z) + f(z)g'(z).

(b) Using the result from part (a), we can show that if Sn is true, then Sn+1 is also true. This establishes that **Sn is true **for all n € N.

(a) To prove the product rule for** complex functions**, we consider two analytic functions f(z) and g(z). By definition, an analytic function is differentiable in a region. We want to show that their product h(z) = f(z)g(z) is also differentiable in that region. Using the limit definition of the derivative, we expand h'(z) as a **difference quotient** and apply the limit to show that it exists. By manipulating the expression, we obtain h'(z) = f'(z)g(z) + f(z)g'(z), which proves the product rule for complex functions.

(b) Given that S₁ is true, which states d = z⁰ for n = 1, we use the product rule from part (a) to show that if Sn is true (d = nzn-1), then Sn+1 is also true. By applying the product rule to Sn with f(z) = z and g(z) = zn-1, we find that Sn+1 is true, which implies that d = (n+1)zn. Since we have shown that if Sn is true, then Sn+1 is also true, and S₁ is true, it follows that Sn is true for all **n € N by induction.**

In conclusion, by proving the product rule for complex functions in part (a) and using it to show the truth of Sn+1 given Sn in part (b), we establish that Sn is true for all n € N.

To find the local **extrema **for the function f(x, y) = x³ - 18xy + y³, we need to find the** critica**l points where the partial derivatives are equal to zero or do not exist.

Let's start by finding the **partial derivatives** of f(x, y):

∂f/∂x = 3x² - 18y

∂f/∂y = 3y² - 18x

Now, we set these partial derivatives equal to zero and solve for x and y:

∂f/∂x = 0: 3x² - 18y = 0 --> x² - 6y = 0 ...(1)

∂f/∂y = 0: 3y² - 18x = 0 --> y² - 6x = 0 ...(2)

From equation (1), we can solve for x in terms of y:

x² = 6y

x = ±√(6y)

Substituting this into equation (2):

(√(6y))² - 6y = 0

6y - 6y = 0

0 = 0

From this, we see that equation (2) does not provide any additional information.

Now, let's consider equation (1). Since x² - 6y = 0, we can substitute x² = 6y into the original function f(x, y) to obtain:

f(x, y) = (6y)³ - 18y(6y) + y³

= 216y³ - 648y² + y³

= 217y³ - 648y²

To find the local extrema, we need to solve 217y³ - 648y² = 0:

y²(217y - 648) = 0

From this equation, we can see that y = 0 or y = 648/217.

If y = 0, then x² = 6(0) = 0, so x = 0 as well. Therefore, we have a critical point at (0, 0).

If y = 648/217, then x = ±√(6(648/217)) = ±√(36) = ±6. Therefore, we have two critical points at (-6, 648/217) and (6, 648/217).

Now, let's classify these critical points to determine the local extrema.

To determine the type of critical point, we can use the second partial derivative test. However, before applying the test, let's compute the **second **partial derivatives:

∂²f/∂x² = 6x

∂²f/∂y² = 6y

At the critical point (0, 0):

∂²f/∂x² = 6(0) = 0

∂²f/∂y² = 6(0) = 0

The second partial derivatives test is inconclusive at (0, 0).

At the critical point (-6, 648/217):

∂²f/∂x² = 6(-6) = -36 < 0

∂²f/∂y² = 6(648/217) > 0

The second partial derivatives test indicates a local **maximum** at (-6, 648/217).

At the critical point (6, 648/217):

∂²f/∂x² = 6(6) = 36 > 0

∂²f/∂y² = 6(648/217) > 0

The second partial derivatives test indicates a local minimum at (6, 648/217).

In summary:

There is a local maximum at (-6, 648/217).

There is a local minimum at (6, 648/217).

There is a critical point at (0, 0), but its classification is inconclusive.

An experiment has a single factor with six groups and three values in each group. In determining the among-group variation, determining the total variation, there are 17 degrees of freedom. a. If SSA = 140 and SST = 224, what is SSW? b. What is MSA? c. What is MSW? d. What is the value of FSTAT?

The answer is SSW = 84.MSA is the** Mean Square Error** for the analysis of variance test of hypothesis for comparing means.

Given, A single factor with six groups and three values in each group. **Degrees of freedom** = 17.

a) If SSA = 140 and SST = 224,

SSW = SST - SSA = 224 - 140 = 84

b) MSA = SSA / (k - 1) = 140 / (6 - 1) = 28

c) MSW = SSW / (n - k) = 84 / (3 * 6 - 6) = 4.67

d) FSTAT = MSA / MSW = 28 / 4.67 = 6.00

Therefore, SSW = 84, MSA = 28, MSW = 4.67 and FSTAT = 6.00

First we have to find SSW = SST - SSA = 224 - 140 = 84

This is the value of within-group variation.

Hence the answer is SSW = 84.

MSA is the Mean Square Error for the analysis of variance test of **hypothesis** for comparing means.

Experiment has single factor with 6 groups with 3 values in each group, hence k = 6.MSA = SSA / (k - 1) = 140 / (6 - 1) = 28.

MSW is Mean Square Error which is the **variance** of the errors in the model.

MSW = SSW / (n - k) = 84 / (3 * 6 - 6) = 4.67

FSTAT = MSA / MSW = 28 / 4.67 = 6.00

Therefore, SSW = 84, MSA = 28, MSW = 4.67 and FSTAT = 6.00.
