Rejecting the null hypothesis when it is true is called a ________ error, whereas not rejecting a false null hypothesis is called a ________ error.
a. Type II; Type I
b. Type I; Type II
c. minor; major
d. significant; nonsignificant
The correct option is b.Type I; Type II.
Rejecting the null hypothesis when it is true is called a type I error, whereas not rejecting a false null hypothesis is called a u type II error.
A type I error occurs when a null hypothesis that is true in the population is rejected. A false positive is an example of this type of error. A type II error occurs if a null hypothesis that is actually false in the population is not rejected. This type of error is known as a false negative.A type II error differs from a type I error in that a type I error rejects the null hypothesis when it is true (i.e., a false positive). The likelihood of making a type I error is equal to the level of significance set for the hypothesis test.

the minute hand of a clock is 6 inches long. how far does the tip of the minute hand move in 15 mintue?
The length of the minute hand is stated as r=6 inches. We are aware that the minute hand will create a 90° angle in 15 minutes. The measurement is 9.4248 inches as a result.
What is an angle?
An angle is a shape made up of two rays that share an endpoint and is known as the vertex of the angle. These rays are known as the sides of the angle. The plane that contains the rays contains the angles created by two rays. The meeting of two planes can also result in an angle. They are referred to as dihedral angles.
The orientation of a line with another line or plane is represented by its angular position. How far the body has been rotated from the reference position is used to measure angular position.

What are the absolute extrema of a linear equation within a closed interval?
According to the functions theory, linear equations have no absolute extrema for all real numbers, but things are different for any closed interval as absolute extrema are the ends of linear function. Now we proceed to evaluate the function at each point:
Absolute maximum
f(- 8) = 12x^2 -11x +2
f(- 8) = 27
Absolute minimum
f(4) = - 3 · 4 + 3
f(4) = - 9

The mass that can rectangular air mattress can support in water before sinking is 97.2 kg
Consider the rectangular air mattress
The length = 2 meter
The width = 0.500 meter
The thickness = 0.100 meters

bag contains 9 real diamonds and 5 fake diamonds. if 9 diamonds are picked from the bag at random, what is the probability that all of them are real?
The probability that all of them are real is 0.01875 or 1.875%
If the diamonds are replaced after each draw:
The probability of drawing a real diamond is 9/14, found by making the numerator the number of real diamonds and adding the total number of diamonds to find the denominator. 5+9 = 14.
To find the probability of all 9 diamonds drawn being real, multiply 9/14 by itself 9 times. = 387420489/ 20661046784. This creates a probability of 387420489/ 20661046784. This cannot be reduced because there is no common factor. To express as a decimal, divide. 387420489/ 20661046784 = 0.01875. To turn this into a percent, multiply by 100. 0.01875*100 = 1.875
Hence, the probability that all of them are real is 0.01875 or 1.875%

a probability distribution has a mean of 22 and a standard deviation of 2. use chebychev's inequality to estimate the probability that an outcome of the experiment lies between 13 and 31. a) 0.9506 b) 0.9917 c) 0.0494 d) 0.0083 e) 0.2222 f) none of the above
Using Chebychev's inequality the probability shows an outcome of the experiment between 13 and 31 is equal to 0.9506.
As given in the question,
Mean 'μ' = 22
Standard deviation 'σ' = 2
Apply Chebychev's inequality we have,
P ( | X - μ | ≤ kσ ) ≥ 1 - (1/k²)
Where 'k' is the constant value.
Estimation of probability with outcome lies between 13 and 31 using Chebychev's inequality is :
P ( 13 < X < 31 )
= P ( 13 -22 < X - μ < 31 - 22 )
= P ( -9 < X - μ < 9 )
= P ( | X - μ |≤ 9)
= P [ |X - μ | ≤ (9/2) ×2 ]
= P( |X - μ | ≤ Kσ)
≥ 1 - ( 1/k²)
here k = 9/2
= 1 - (1 / (9/2)²)
= 1 - 4/81
= (81 -4) / 81
= 77/ 81
= 0.9506
Therefore, the probability for which outcome lies between 13 and 31 using Chebychev's inequality is equal to 0.9506.

What is equation straight line?
Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.
Given that a= -1.24 and b=33.966, the regression equation is y= axe + b y= -1.24x + 33.966.
Here, "y" stands for the maximum number of situps an individual may perform, and "x" stands for the daily television viewing hours.
The estimated number of situps for a person who watches x=2 hours of TV is y=-1.24*2 + 33.966 y= -2.48 + 33.966 y= 31.486

The top and bottom margin of a poter are 6 cm and the ide margin are each 4 cm. If the area of printed material on the poter i fixed at 380 quare centimeter, find the dimenion of the poter with the mallet area
The dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.
Explain the term rate change of area?We understand that we are attempting to find the minimum of both the area function because we are instructed to locate the smallest area.Let "W" represent the poster's overall width and "H" represent its overall height.Area A = H.W
Its printed material is either W - 4(2) or W - 8.
Its printed material is H - 6(2)
height = H - 12
The printed area is therefore (W - 8)(H - 12) = 380.
(W - 8)(H - 12) = 380
WH - 12W - 8H + 96 = 380
W(H - 12) - 8H = 284
W = (284 + 8H)/(H - 12)
Put the values in the area;
A(H) = H(284 + 8H)/(H - 12)
A(H) = (284H + 8H²)/(H - 12)
Differentiate with respect to H to find the rate change of area.
A'(H) = [(284 + 16H)(H - 12) - (284H + 8H²)(1)]/(H - 12)²
A'(H) = (284H - 3408 + 16H² - 192H - 284H - 8H²)/(H - 12)²
A'(H) = (8H² - 192H - 3408)/(H - 12)²
A'(H) = 8(H² - 24H - 426)/(H - 12)²
Put A'(H) = 0
8(H² - 24H - 426)/(H - 12)² = 0
Solving;
H = 35. 87 cm
Thus, W = 25.63 cm
Thus, the dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.

Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).
Assume the data is from a normally distributed population.
Answer as a tri-linear inequality accurate to 3 decimal places.
A tri-linear inequality for the estimate of the drug that would lower a typical patient's systolic blood pressure (using a 90% confidence level) is; 53.3 ≤ x-bar ≤ 58.3.
Explain the term tri-linear inequality?Equal does not imply inequality. Tri signifies three. The range is defined in terms of inequalities by the tri-linear inequality.For the stated question-
Average of reduction in systolic blood pressure μ = 55.8.
Standard deviation s = 7.9.
Sample of size n = 29
The confidence interval is estimated as-
μ - t₀.₀₅(s/√n) ≤ x-bar ≤ μ + t₀.₀₅(s/√n)
Put the values-
55.8 - t₀.₀₅(7.9/√29) ≤ x-bar ≤ 55.8 + t₀.₀₅(7.9/√29)
On simplifying,
53.3 ≤ x-bar ≤ 58.3

The cost of one kilogram of each type of candy is 9 dollars per kilogram and 4 dollars per kilogram.
Given that,
Erika spent $21.00 at a candy store to purchase 3 kilograms of cinnamon red hots and 1 kilogram of gummy bears. Irene spent $39.00 on 3 kilograms of gummy bears and 3 kilograms of cinnamon red hots.
We have to find how much would one kilogram of each kind of candy cost.
We know that,
Let's change the price of cinnamon red hots per kg to c and the price of gummy bears per kg to b.
3c+1b=21
3c+3b=39
By substitution method
-3c-b=-21 (Multiply one of the equation's terms by -1 to eliminate c.)
3c+3b=39
We get
2b=18
b=9 dollars per kilogram
To find c you can plug the value of b back into one of the equation above and 3c+9=21 which lead to 3c =12 so c=4 dollars per kilogram.
Therefore, the cost of one kilogram of each type of candy is 9 dollars per kilogram and 4 dollars per kilogram.
