2. Consider the dataset from Table B.12 and it can be loaded from R package MPV (table.b12). The response variable y = PITCH is the result of a carbon analysis on the gear pitch for a cross-sectioned part. Use all possible regressions and the Cp criterion to find an appropriate regression model for these data. Investigate model adequacy using residual plots. Provide interpretations/explanations.
