Question:

Use the ANOV table given in Table 12.28 for a balanced experiment having three treatments to answer the following questions.

(a) How many replicates of each treatment were used in this experiment?

(b) Test the hypothesis of the equality of the treatment means at the ???? = 0.01 level.

(c) Estimate the standard deviation of the error term in the model.

(d) Determine the number of pairwise comparisons needed to separate the three treatment means.

(e) Determine the Bonferroni distance ???? for separating the treatment means when the experimentwise error rate is ???????? = 0.06.

(f) If ????̄1• = 120.7, ????̄2• = 139.3, and ????̄3• = 147.4, use the Bonferroni procedure to separate the treatment means with an experimentwise error rate of ???????? = 0.05.
(g) Summarize the separation of the treatment means using the underline notation.
