Consider the "mtcars" dataset "built-in" with R. Perform standard Stepwise Regression in R using AIC as the search criterion, starting with the model mpg ~ 1 and searching up to mpg ~wt + drat + disp + qsec. What is the subset of predictors (from amongwt, drat, disp, and qsec) that the algorithm came up with? Now do the same thing using the BIC criterion instead. Which subset of these four predictors do you get now? For both of these two sub-questions in this question (Question 4) you only need to give the corresponding subset of predictors as your answer. You do not need to include any code, code output, or explanation with your answer for this question.
