1. We test for heterogeneity of variance to determine whether we have satisfied one of the assumptions of the t-test. Suppose we found heterogeneity of variance. What would that tell us other than the fact that we violated an assumption of the t-test?
2. What are the critical value or values for the following conditions?

c) 1 tailed z test, =.05

H1 predicts an increase in the meand) 2 tailed z test, =.05

e) 1 tailed t test, df=10, =.01f) 2 tailed t test, df=40, =.01

H1 predicts an increase in the mean

NOTE: Take 1 point off for every mistake.
