Assume that we draw two random samples of students from Coles college of Business. One group includes 10 economics majors and another includes 30 finance majors. From these two groups we obtain the following statistics regarding the performance on the final calculus exam: Economics: the average value is 87, the standard deviation is 9; Finance: the average value is 91, the standard deviation is 5. Please conduct a 90% significance test for the equality of the two population variances and state if such a test would reject or not the null hypothesis that the two variances are equal.
