Suppose that there is sufficient evidence to reject H0: 1 = 2 = 3 using a one-way

Suppose that there is sufficient evidence to reject H0: µ1 = µ2 = µ3 using a one-way ANOVA. The mean square error from ANOVA is determined to be 26.2. The sample means are x̅1 = 9.5, x̅2 = 9.1, x̅3 = 18.1, with n1 = n2 = n3 = 5.
Use Tukey's test to determine which pairwise means are significantly different using a family wise error rate of α = 0.05.
