For 40 candidates for 4 sales manager positions, applicants are given a subjective Rating by a screening panel. Then, a number of other variables are scored by an HR software program. Below is backward elimination output (with some deletions) for a study of the regressions of Rating vs. these other variables. Use this output for Problems 1-2.
