Statistics: Regression Analysis – #396


Question: Stocks and Super Bowl. Data Set 25 (see attached Excel spreadsheet, if you need it)

The Data Set 25 includes pairs of data for the Dow-Jones Industrial Average (DJIA) high value and the total number of points scored in the Super Bowl for 21 different years. Excel was used to find the value of the linear correlation coefficient is r= -0.133 and the regression equation is y-hat= 53.3 – 0.000442x, where x is the high value of the DJIA. Also, the mean number of Super Bowl points is 51.4. What is the best predicted value for the total number of Super Bowl points scored in a year with a DJIA high of 1200?
