Question: 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

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 σ2 is 9.12, and the sample means follow:
1 = 101.6 2 = 98.4 3 = 112.3
4 = 92.9 5 = 104.2 6 = 113.8
a. Give the value of v that you would use to make pair wise comparisons of the treatment means for a = .05.
b. Rank the treatment means using pair wise comparisons.
