Basketball: Fouls Data for this problem are based on information from STATS Basketball Scoreboard. It is thought that basketball teams that make too many fouls in a game tend to lose the game even if they otherwise play well. Let x be the number of fouls that were more than (i.e., over and above)

the number of fouls made the opposing team made. Let y be the percentage of times the team with the larger number of fouls won the game.

(a) through (e), given x 5 13, y 5 154, x2 5 65, y2 5 6290, xy 5 411, and r < 0.988.

(f) If a team had x 5 4 fouls over and above the opposing team, what does the least-squares equation forecast for y?
