Equation from d

DIFF= -4.59244 + 0.94156 * HIT - 1.72368 * ERR

Problem 1 (Softball Team Data). The STAT/MATH/CS co-ed softball team has participated in intramural co-ed softball for 32 years, playing over 450 games during that time. Considering the composition of the team, it is perhaps not surprising that the team has compiled some statistics from those games. Their team captain was wondering what relationship, if any, there was between how many hits and errors the team made in a game and how well they did. He consulted the dataset, and determined that the team had played 466 games over its history. For each game are listed RUNS (his team's score), ORUN (the opposing team's score), HIT (the number of hits obtained by his team), ERR (the number of errors committed by his team), and RES (the result; W, L, or T, depending on whether his team won, lost, or tied the game). The data set is attached in a file called softball.txt. It contains a header line and 466 lines of data. a (f) Suppose that one uses the regression equation of (d) to predict the outcome of a game by declaring the game a victory if the predicted DIFF > 0) and a loss if predicted DIFF 0) and a loss if predicted DIFF
