Consider the following calculations for a one-way analysis of variance from a completely randomized design with 20 total observations equally divided into 4 treatments. The response variable is sales in millions of dollars, and the four treatment levels represent the four regions that the company serves.
MSE = 101.25 = 39 = 33 = 43 = 49 = 31
Perform a pairwise comparison between treatment mean 3 and treatment mean 4 by computing a Tukey 90 percent simultaneous confidence interval.
