Using the data file for Exercise 17.55:
a. Apply stepwise regression with the rating by board member 1 as the dependent variable and the ratings by the other 8 members as the set of independent variables from which to select. Interpret the results.
b. Using only the independent variables introduced during the stepwise regression, perform a multiple regression analysis.
c. Compare the results in parts (a) and (b).
We suggest that Minitab users specify alpha-to-enter as 0.05 and alphato- remove as 0.10.
