Design of Experiments, ANOVA, Coded Factor Level

I need a couple of good example problems worked and done fully. The Book is Design of Experiments by Montgomery. Prefer results in Minitab.

Perform DOE

a) Estimate factor levels

b. Use ANOVA to confirm part A

c. Write Down a regression model for predicting tool life (in hours)

d. Anlayze the residuals Any obvious problems?

E. Based on analysis which coded factor levels should be used?
