Question

Making Predictions. Use the given data to find the best predicted value of the dependent variable. Be sure to follow the prediction procedure described in this section. Stocks and Super Bowl The Dow Jones Industrial Average (DJIA) high value and the total number of points scored in the Super Bowl were recorded for 21 different years. Excel was used to find that the value of the linear correlation coefficient is r = 0.133 and the regression equation is

y^ =3.30.000442x , 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?

Explanation / Answer

Equation:

y^ =3.30.000442x

if x = 1200

y^ = 3.3 0.000442 * 1200

y^ = - 3.8304
