Regression Analysis
The Philadelphia Eagles would like to know what motivates fans to attend the games. Coach Andy Reid has gathered data on attendance, Eagles and Opponents win/loss percentage, number of games played, temperature, and whether or not his troublesome wide receiver Terrell Owens has committed some atrocity (example, called QB Donovan McNabb an idiot or some asinine public display) in the week before the game (1 = yes, 0 = no).

a) Does the Eagles win/loss percentage count?
b) Does TO’s behavior count? If so how much? Should the team dump him for attendance causes?
c) Is multi-co linearity a problem in this analysis?
d) What would be the 95% confidence interval for an attendance prediction be when the Eagles had won 75% of their games, their opponents had won 50%, they had played 8 games, the temperature was 49 degrees and TO had said earlier in the week that both Reed and Donovan should be sent to Iraq.
