8. A sample of difference scores from a repented-

measures experimen has a mean of Mp. = 5 with u vanance of $ - 64.

w. If n = 4, is this sample sufficient to reject the null hypothesis using a two-tailed ies with a = 053

b. Would you reject Ha if n- 167 Again. assume two-tailed test with o - 05

e. Explain how the size of the sample indhiences the likelihood of finding a significant mean difference
