An independent random sampling design was used to compare the means of six treatments based on samples of four observations per treatment. The pooled estimator of is 9.12, and the sample means follow:

a. Give the value of v that you would use to make pairwise comparisons of the treatment means for α = .05.

b. Rank the treatment means using pairwise comparisons.
