The following hypotheses are given: Ho: s2 sub 1 = s2 sub 2 H1: s2 sub 1 = s2 sub 2 A random sample of five observations from the first population resulted in a standard deviation of 12. A random sample of seven observations from the second population showed a standard deviation of 7. At the .01 significance level, is t
