During the National Football League (NFL) season, Las Vegas oddsmakers establish a point spread on each game for betting purposes. The final scores of NFL games were compared against the final points spreads and the difference between the game outcome and point spread (called a point-spread error) was calculated for 240 NFL games and the mean and standard deviation of the differences were -1.6 and 13.3 respectively. Test to see if the true mean point- spread error differs from 0 at a 1% level of significance.
