Question: For the same data set considered in Problem 2 (and employing the accompanying computer output), use the stepwise regression approach to find the best regression

For the same data set considered in Problem 2 (and employing the accompanying computer output), use the stepwise regression approach to find the best regression models of SBP on QUET, AGE, and QUET × AGE for smokers and nonsmokers separately. (Use α = .05.) Compare the results for each group here with those obtained for Problem 2(d).
