Consider a multiple regression model for predicting the total number of runs scored by a Major
LeagueBaseball (MLB) team during a season.
Model 1. Using data on number of walks (x), singles (x2), doubles (x3), triples (x4), and home runs (xs) for
each of the 30 teams during the 2017 MLB season, a first-order model for total number of runs scored (y) was
fit. The selected results are shown in the SAS printout below.

Model 2. Using data on number of walks (x1), singles (x2), doubles (x3), triples (x4), home runs (xs), stolen
bases (x6), times caught stealing (x7), strike-outs (xs), and ground outs (x9) for each of the 30 teams during
the 2017 MLB season, a first-order model for total number of runs scored (y) was fit. The selected results are
