The same microeconomics examination was given to students at two different universities. The results were as follows:
1 = 75, S21 = 9.0, n1 = 50
2 = 70, S22 = 7.2, n2 = 40
where the 's denote the grade averages in the two samples, the S2's, the two sample variances; and the n's, the sample sizes. How would you test the hypothesis that the population variances of the test scores in the two universities are the same? Which probability would you use? What are the assumptions underlying that
