Expert Answer

Step 1

(a)

The method of transformation may transform either one or both of the response and predictor variables, in an attempt to satisfy the assumptions of the regression model.

Thus, the statement “In using the method of transformations, we should only transform the predictor variable to straighten a scatterplot.” is False.

Step 2

(b)

The conditional distribution of the response variable depends on the predictor variable and not on any transformation of the predictor variable. Whatever transformation is performed on the predictor variable, the conditional distribution of the response variable will continue t...
