A sample of 60 items from population 1 has a sample variance of 8 while a sample of 40 items from population 2 has a sample variance of 10. If we want to test whether the variances of the two populations are equal, the test statistic will have a value of

H0:

H1:

The statistic would be given by:

Step-by-step explanation:

Information given

represent the sample size 1

represent the sample size 2

represent the sample variance 1

represent the sample variance 2

The statistic to check the hypothesis is given by:

Hypothesis to test

We want to test if the two variances are equal, so the system of hypothesis are:

H0:

H1:

The statistic would be given by:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
