Essay

Is the number of games won by a major league baseball team in a season related to the team's batting average? Data from 14 teams were collected and the summary statistics yield: $\sum y=1,134, \sum x=3.642, \sum{y} 2=93,110, \quad \sum{x}^{2}=.948622, \text { and } \sum x y=295.54$
Find the least squares prediction equation for predicting the number of games won, y, using a straight-line relationship with the team's batting average, x.
