Suppose an ANOVA has been performed on a completely randomized design containing six treatment levels. The mean for group 3 is 15.85, and the sample size for group 3 is eight. The mean for group 6 is 17.21, and the sample size for group 6 is seven. MSE is .3352.The total number of observations is 46. Compute the significant difference for the means of these two groups by using the Tukey-Kramer procedure. Let α = .05.
