2. 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 2 is 9.12, and
the sample means follow: These are 6 means given
below.
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 that you would use to make pairwise
comparisons of the treatment means for a $ .05.
b. Rank the treatment means using pairwise comparisons
