We are interested in determining whether the variances of the sales at two music stores (A and B) are equal. A sample of 25 days
Alexandra [31]

Answer:

H0: \sigma^2_1 = \sigma^2_2

H1: \sigma^2_1 \neq \sigma^2_2

Now we can calculate the statistic like this:

F=\frac{s^2_A}{s^2_B}=\frac{30^2}{20^2}=2.25

And the best option would be:

b. 2.25

Step-by-step explanation:

Information given

n_A = 25 represent the sample size A

n_B =16 represent the sample size B

s_A = 30 represent the sample deviation for A

s_B = 20 represent the sample deviation for B

Solution to the problem

We want to test if the variation for A it's equal to the variation for B, so the system of hypothesis are:

H0: \sigma^2_1 = \sigma^2_2

H1: \sigma^2_1 \neq \sigma^2_2

Now we can calculate the statistic like this:

F=\frac{s^2_A}{s^2_B}=\frac{30^2}{20^2}=2.25

And the best option would be:

b. 2.25
