Question

he National Football Leaque (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the conference (Cont), average number of passing yards per attempt(Yds/Att), the number of interceptions thrown per attempt (Inset), and the percentage of games _ (Wm%) for random un ple of 16 NF, tram, for a eason Team Arizona Cardinals 6.4 7.3 7.3 5.2 7,.3 8.8 6 5.7 4.6 5.7 0.042 0.022 0.034 0.028 49.8 62.6 37.4 Atlanta Falcons Carolina Panthers Cincinnati Bengals Detroit Lions Green Bay Packers Houstan Texans Indianapolis Colts Jacksonville Jaguars AFC 62.5 015 0.020 0.029 032 0.035 0.020 0.022 93.7 AFC 12.6 31.3 18.5 81.5 81.5 AFC Minnesota Vikings New England Patriots New Orieans Saints Oakland Raiders San Francisco 49ers Tennessee Titans 0.010 0.026 0.041 81.2 56.4 AFC 6.6 attempt isthe independent าเa tie (to 3 decirnais).

Answer 1

$\hat{y}=-57.640+16.25*Yds/Att$

R-squared = 0.59 or 59% of the variation in y is defined by this model.

The p-value of f-statistic is less than 0.05 and R-squared is also ok. We can say the model is a good fit.

B)

$\hat{y}=100.9169-1680.11*(Int/Att)$

R-squared = 0.44 or 44% of the variation in y is defined by this model.
