Question

Exhibit 11-7  We want to test the hypothesis that population B has a smaller variance than population A.
-Refer to Exhibit 11-7. The null hypothesis

Quizplus · Accepted Answer

The null hypothesis is that the variances of both populations are equal. If the test results in a higher F-statistic and a p-value greater than the chosen level of significance, we fail to reject the null hypothesis. Therefore, we would not reject the null hypothesis and conclude that there is no significant evidence to suggest that the variance of population B is smaller than that of population A.
