Given a normal distribution with u = 75 and o = 40, if you select a sample of n = 16, a) what is the probability that the sample mean is above 95? (4 d.p.) b) What is the value, of which there is 97.5% chance that a sample mean is less than that value? (1 d.p.)

Answers

Answer:

a) 0.0228

b) 94.6

Step-by-step explanation:

The formula for calculating a z-score when you are given a random.number of samples is z = (x-μ)/σ/√n

where x is the raw score

μ is the population mean

σ is the population standard deviation

n = random number of samples

Given a normal distribution with u = 75 and o = 40, if you select a sample of n = 16,

a) what is the probability that the sample mean is above 95? (4 d.p.) b)

= x = 95

Hence:

z = 95 - 75/40/√16

= 20/40/4

= 20/10

= 2

Probability value from Z-Table:

P(x<95) = 0.97725

P(x>95) = 1 - P(x<95) = 0.02275

The probability that the sample mean is above 95 to 4 decimal places = 0.0228

b) What is the value, of which there is 97.5% chance that a sample mean is less than that value?

97.5% chance = z score for the confidence interval = 1.96

Hence:

z = (x-μ)/σ/√n

1.96 = x - 75/40/√16

1.96 = x - 75/ 40/4

1.96 = x - 75/10

Cross Multiply

1.96 × 10 = x - 75

19.6 = x - 75

x = 19.6 + 75

x = 94.6

The value, of which there is 97.5% chance that a sample mean is less than that value is 94.6

Solving for variable 'x'.

Reorder the terms:

Combine like terms: -18 + -6 = -24
-24 + -18x + 6x2 = 6 + -6

Calculate the value of the test statistic (round to 4 decimal places).
Calculate the p-value (round to 4 decimal places).

Answers

Answer:

The test statistics is  [tex]z =  -1.56 [/tex]  

The p-value is   [tex]p-value =  0.05938 [/tex]

Step-by-step explanation:

From the question we are told  

   The West side sample  size is [tex]n_1  =  578[/tex]

    The  number of residents on the West side with income below poverty level is [tex]k  = 76[/tex]

    The East side sample size  [tex]n_2=688[/tex]

  The  number of residents on the East side with income below poverty level is [tex]u  = 112[/tex]

   The null hypothesis is  [tex]H_o  :  p_1 = p_2[/tex]

    The alternative hypothesis is  [tex]H_a :  p_1 <  p_2[/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _1 = \frac{k}{n_1}[/tex]

=>   [tex]\^{p} _1 = \frac{76}{578}[/tex]

=>   [tex]\^{p} _1 =  0.1315 [/tex]

Generally the sample proportion of  West side is  

     [tex]\^{p} _2 = \frac{u}{n_2}[/tex]

=>   [tex]\^{p} _2 = \frac{112}{688}[/tex]

=>   [tex]\^{p} _2 =  0.1628 [/tex]

 Generally the pooled sample proportion is mathematically represented as

    [tex]p = \frac{k + u}{ n_1 + n_2 }[/tex]

=>  [tex]p = \frac{76 + 112}{ 578 + 688 }[/tex]

=>  [tex]p =0.1485[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2}  ]}  }[/tex]

=> [tex]z = \frac{ 0.1315  - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688}  ]}  }[/tex]  

=> [tex]z =  -1.56 [/tex]  

Generally the p-value  is mathematically represented as

          [tex]p-value =  P(z <  -1.56 )[/tex]

From z-table  

         [tex]P(z <  -1.56 ) =  0.05938[/tex]

So

     [tex]p-value =  0.05938 [/tex]

Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they have sold a total of 45 items and earned $195. If hot dogs cost $4 and hamburgers cost $5, how many did they sell of each?

What would be a system of equations for the scenario above?

Answers

Answer:

15 hamburgers were sold and 30 hotdogs were sold.

The systems of equations are x + y = 45 and 4x + 5y = 195.

Step-by-step explanation:

Let's make two equations.

x + y = 45

This represents the total of hotdogs and hamburgers sold

4x + 5y = 195

This represents the amount of money made for each food.

These are systems of equations, when you use 2 equations to solve a problem. I will use the strategy, Elimination for the following systems of equations. Anyways the goal is to multiply a number to x + y = 45 to cancel out one of the variables in 4x + 5y = 195. In other words, when we add these equations, the sum of the xs or ys will equal 0.

Let's multiply -5 to both x and y.

Now we have -5x -5y = -225 + 4x + 5y= 195

We will end up with -x = -30. This means that x = 30.

Now that we know x = 30, we can plug in 30 as x in one of the equations. I will plug in 30 into x + y = 45. 30 + y = 45.

Solve for y in 30 + y = 45, so y=15.

This means 15 hamburgers were sold and 30 hotdogs were sold.

What is slope ?

Slope is the rate of change.It can also be thought of as rise over run.

According to the given question slope(m) is 1/4 and point is (-8,6).

We know equation of a line in slope intercept form is y = mx + b, where b is the y intercept.

∴ 6 = (-8)1/4 + b.

Answers

[tex]y = 1.38x + 12.60[/tex]

Step-by-step explanation:

the 12.60 is going to be charged every months no matter what it's fixed so that's why it's added! the 1.38 is a rate, so how many cubic inches she uses in increments of 100 she will be charged so that depends on how much she uses in addition to that 12.60for example she uses 700 cubic feet of water once month well (x) will be 7 because u divide it by 100 and it'll give u ur "x". put it into the formula and it'll give the price she'll have to pay. 1.38(7) + 12.60 and this will equal $21.70 !

Answer:

Explanation:

For g(2), just substitute 2 in for the x, multiply, and simplify.

g(x) = 5-9(x)

g(2) = 5-9(2) = 5-18 = -13

For f(g(2)), substitute this output in for x, multiply, and simplify.

WXYZ is a kite. Angle WXY has a measure of 133 degrees and angle ZWX has a measure of 60 degrees. Find the measure of angle ZYW.

Answers

Answer:

ZYW = 17.

Step-by-step explanation:

ZYW = XYW = 180 - 133 + 30(sum of angles in a triangle) = 17.

The measure of angle ZYW is 17.

Given that,

The Angle WXY has a measure of 133 degrees.And, the angle ZWX has a measure of 60 degrees.

Based on the above information, the calculation is as follows:

= 180 - 133 - 30

= 17

Also ZYW = XYW

Therefore we can conclude that the measure of angle ZYW is 17.

In these questions you're being asked to multiply mixed numbers. The easiest way to do this is to convert the mixed numbers to improper fractions, and then multiply them in that form.

For the first question:

[tex]1\frac{3}{5} = \frac{8}{5} ; 1\frac{2}{5} =\frac{7}{5} \\[/tex]  To convert the mixed numbers to improper fractions, you just     multiply the denominator by the whole number, and then add it to the current  numerator, forming the new numerator. The denominator stays the same.

[tex]\frac{8}{5} *\frac{7}{5} = \frac{56}{25}[/tex]       Next, multiply together the numerators, and then multiply together the denominators.
