Suppose that there is sufficient evidence to reject H0: m1 = m2 = m3 = m4 using a one-way ANOVA. The mean square error from ANOVA is determined to be 373. The
sample means are x1 = 78, x2 = 64, x3 = 70, x4 = 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.
