Suppose that there is sufficient evidence to reject

H0: µ1 = µ2 = µ3 = µ4 using a one-way ANOVA. The mean square error from ANOVA is determined to be 373. The sample means are x̅1 = 78, x̅2 = 64, x̅3 = 70, x̅4 = 47, with n1 = n2 = n3 = n4 = 31. Use Tukey's test to determine which pairwise means are significantly different using a familywise error rate of a = 0.05.
