In exercise 12.28, we have the following data concerning wear of a bearing:

(a) The following model may be considered to describe this data: y i = 00 + ?₁x_l, + ?₂x₂ + ?₁₂x_1,?x₂i + ? i, for i = 1, 2... 6. The %X2 is an "interaction"' term. Fit this model and estimate the parameters.

(b) Use the models (x), (x₁, x₂), (x₂). (x₁, x₂, x₁x₂) and compute PRESS, Cp, and s" to determine the 'best'' model.
