Chapter 13.1, Problem 24ES

Baseball In baseball, a batter’s slugging average, which measures the hatter’s power as a hitter, is a type of weighted mean. If s, d, t, and h represent the numbers of singles, doubles, triples, and home runs, respectively, that a player achieves in n times at bat, then the player’s slugging average is $\frac{s+2d+3t+4h}{n}$.

Find the players slugging average for the season or seasons described. Slugging averages are given to the nearest thousandth.

Babe Ruth, over his 22-year career, was at bat 8399 times and hit 1517 singles, 506 doubles, 136 triples, and 714 home runs.
