Consider a Two-Way Analysis of Variance Experiment with Treatment Factors

question 107

Short Answer

Consider a two-way analysis of variance experiment with treatment factors A and B. The results are summarized below.
If the mean response for level 1 of factor A is 31.5 and the mean response for level 2 of factor A is 22.5, calculate a Tukey simultaneous 95 percent confidence interval for this difference.
