Question:

Refer to Exercise 15.22.
a. Write a model for this experimental setting.
b. Estimate the parameters in the model.
c. Display a complete analysis of variance table. Use α = .05.
d. What conclusions can you draw concerning the best mixture from the four tested?
e. Compute the relative efficiency of the randomized block design compared to a completely randomized design. Interpret this value. Were the blocks effective in reducing the variability in experimental units? Explain.
