An engineer suspects that the surface finish of a metal part is influenced by the feed rate
Question:
An engineer suspects that the surface finish of a metal part is influenced by the feed rate and the depth of cut. He selects three feed rates and four depths of cut. He then conducts a factorial experiment and obtains the following data:
(a) Analyze the data and draw conclusions. Use α = 0.05.
(b) Prepare appropriate residual plots and comment on the model's adequacy.
(c) Obtain point estimates of the mean surface finish at each feed rate.
(d) Find the P-values for the tests in part (a).
