The results of an experiment comparing the cycle lengths of three different brands of washing machines (N=33) indicated an overall mean square error of 2.58. The researcher believes that the brands 1 and 2 may be the most different as they have mean cycles of 31.8 (n=12) and 35.9 (n=10). Using an alpha of 0.05, what would be the result of the Tukey-Kramer formula?
