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:
$$\sum y = 1,134 , \sum x = 3.642 , \sum y ^ { 2 } = 93,110 , \sum x ^ { 2 } = .948622 , \text { and } \sum x y = 29$$
Assume $\hat { \beta } 1 = 455.27$. Estimate and interpret the estimate of $\sigma$. 54
