Use the data in Problem 4.3, pp. 157. Answer all parts of questions.
Analyze this as a randomized block design. Provide the ANOVA table. Interpret the results of the main test of interest, using alpha=0.05.
Assess model assumptions.
Run and interpret the results of a Tukey multiple comparison Post Hoc analysis on the main effect. Based on the results of the main test, is it necessary
Provide an estimate of the error standard deviation σ. Provide estimates for the treatment effects (the τ’s, must sum to zero.).
Suppose this was actually a pilot study. Using the estimates in part d) in your calculation of the power, decide how many bolts (number of blocks) the chemist would need in a larger study, if she desired a power of at least .95 when using alpha=0.05. Show necessary workare:
