Question:
(a) Suppose H0: μX = μY is to be tested against H1: μX ≠ μY. The two sample sizes are 6 and 11. If sp = 15.3, what is the smallest value for | x̅ − y̅| that will result in H0 being rejected at the α =0.01 level of significance?
(b) What is the smallest value for x̅ − y̅ that will lead to the rejection of H0: μX = μY in favor of H1: μX > μY if α = 0.05, sP = 214.9, n =13, and m =8?
