Question: Ten major college football bowl games were played in January 2010. with the University of Alabama beating the University of Texas 37 to 21 to become the national champion of college football. The results of the ten bowl games are shown below (USA Today. January 8, 2010). The predicted winning point margin was based on Las Vegas betting odds approximately one week before the bowl games were played. For example. Auburn was predicted to beat Northwestern in the Outback Bowl by five points. The actual winning point margin for Auburn was three points. A negative predicted winning point margin means that the team that won the bowl game was an underdog and expected to lose. For example, in the Rose Bowl, Ohio State was a two-point underdog to Oregon and ended up winning by nine points.

a. Develop a scatter diagram with predicted point margin on the horizontal axis.

b. What is the relationship between predicted and actual point margins?

c. Compute and interpret the sample covariance.

d. Compute the sample correlation coefficient. What does this value indicate about the relationship between the Las Vegas predicted point margin and the actual point mar-gin in college football bowl games?
