Football owners are constantly in competition for good players. The more wins, the more likely that the team will provide good business returns for the owners. The resources that each team has in the National Football League (NFL) vary, but the draft system is designed to counteract the advantages that wealthier teams may have. Is it working or does the size of the payroll matter? In other words, is there a relationship between total team salary and the performance of teams in the NFL? For the 2012-2013 season, data in terms of wins and total team salaries were collected from the 32 teams in the league.

Question 3: Provide the estimated linear regression equation.

Question 4: If one team spends $10 million more than another on salaries, how many more games on average would you predict them to win?

Question 5: If a team spent $120 million on salaries and won 8 games, would they have done better or worse than predicted?
