Question

Consider the following calculations for a one-way analysis of variance from a completely randomized design with 20 total observations. The response variable is sales in million of dollars and four treatment levels represent the four regions that the compant serves.

MSE=101.25

YBar overall = 39

YBar 1 = 33

YBar 2 = 43

YBar 3 = 49

YBar 4 = 31

A) Perform a pairwise comparison between treatment mean 1 and treatment mean 4 by computing a Tukey 95% simultaneous confidence interval

B) TRUE OR FALSE: based on the Tukey anaylsis these is a signifigant difference between the means for variables 1 and 4
