A teacher wishes to compare two different groups of students with respect to their mean time to complete a standardized test. The time required is determined for each group. The data summary is given below. Test the claim at alpha = 0.10, that there is no difference in variance. Give the critical region, test statistic value, and conclusion for the F test.
n1 = 40     s1 = 44
n2 = 60     s2 = 74
<!--filtered--> = 0.10
·         State the null and alternate hypotheses
