The table below shows the number of interceptions thrown during the season by seven randomly selected National Football League teams and the number of games those teams won during the season.



Use the NFL team data to perform a hypothesis test to determine if the population correlation coefficient is less than zero using α = 0.05.

For a one-tail test with α = 0.05 and 7 - 2 = 5 degrees of freedom, tα = -2.015. Because t = -3.02 is less than tα = -2.015, we reject the null hypothesis. Based on our sample, the population correlation coefficient between wins and interceptions is less than zero and statistically significant.
