Question

It was stated in this section that the F-test is very sensitive to minor departures from the assumptions. Repeat Exercise 10. 139 using N(100, 20) and N(120, 30). Notice that the only change from Exercise 10. 139 is the seemingly slight increase in the standard deviation of the second population. Answer the same questions using the same kind of information and you will see very different results.
