Some statisticians have done (semi-serious) studies to connect Super Bowl scores to the performance of the Dow Jones Industrial Average (DJIA). (For example, see summers, P.M.: The Super Bowl Theory: Fourth and Long, College Mathematics Journal 31.) Below is a table showing the total points scored in recent Super Bowls and the % change in the DJIA for a sample of six years?
a. Compute the sample covariance for Super Bowl points and % change in the DJIA.
b. Compute the sample correlation coefficient here. (The sample standard deviation, s x, of the Total Points data is 8.65; the sample standard deviation, s y, for the DJIA data is 19.34.)
