Answer 1

The question deals with hypothesis testing for the comparison of variances and pass rates using an F-test and a test of two proportions. The null hypothesis is typically not rejected unless there's sufficient evidence, characterized by a p-value smaller than the significance level.

Step-by-step explanation:

The question pertains to a statistical test for equality of variances and pass rates between two different samples. In part 80, the hypothesis testing is conducted by comparing variances using an F-test, where H0 represents the null hypothesis that the variances are equal, while Ha states that they are not.

One compares the F statistic to the critical value at the 0.10 significance level to determine whether to reject H0. The decision is not to reject H0 if the p-value is greater than 0.10, indicating insufficient evidence to say that there is a difference in variances.

The student's subsequent questions deal with identifying whether this statistical test is about means or proportions. In the case of Math 1A and Math 1B, as well as the homeowners' example, one would use a test of two proportions because it involves the pass rates and proportions of homeowners.
