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 squiggley a = 0.10, that there is no difference in variance. Give the critical region, test statistic value, and conclusion for the F test.
n1 = 24 s1 = 21
n2 = 40 s2 = 39
squiggley a = 0.10
a) State the null and alternate hypotheses
b) Determine which test statistic applies, and calculate it
c) Determine the critical region
d) State your decision: Should the null hypothesis be rejected?
