2. An independent random sampling design was used tocompare the means of six treatments based on samples of fourobservations per treatment. The pooled estimator of ï³2 is 9.12, andthe sample means follow: These are 6 means givenbelow.
Mean x 1 =101.6 Mean x 2 = 98.4 mean x 3=112.3
Mean x 4 =92.9 Mean x 5= 104.2 Mean x 6=113.8
a. Give the value of ï·ï€ that you would use to make pairwisecomparisons of the treatment means for a $ .05.
b. Rank the treatment means using pairwise comparisons
