Is the Number of Games Won by a Major League $$\sum y = 1,134 , \sum ^ { x = 3.642 , } \sum y ^ { 2 } = 93,110 , \sum ^ { 2 } = .948622 , \text { and } \sum x y = 295.54$$

Essay

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