Question:

Suppose we would like to use the model developed in Problem 2.1 to predict the number of games a team will win if it can limit opponents' yards rushing to 1800 yards. Find a point estimate of the number of games won when $x_{8}=1800$. Find a $90 %$ prediction interval on the number of games won.


Data From Problem 2.1

Table B. 1 gives data concerning the performance of the 26 National Football League teams in 1976. It is suspected that the number of yards gained rushing by opponents $\left(x_{8}\right)$ has an effect on the number of games won by a team $(y)$.
