Question:

You are given the following null and alternative hypotheses H0: s21

… s22 HA: s21 7 s22 and sample information Sample 1 Sample 2 n1 = 21 n2 = 12 s21

= 345.7 s22

= 745.2

a. If a = 0.01, state the decision rule for the hypothesis. (Be careful to pay attention to the alternative hypothesis to construct this decision rule.)

b. Test the hypothesis and indicate whether the null hypothesis should be rejected.
