A group of season ticket holders wants to forecast attendance at National Football League (NFL) games for the upcoming season. One ticket holder argues that using the population of the United States as the only independent variable would explain as much as using both the United States population and the percent change in disposable income (per capita) as independent variables. Another ticket holder argues that using the percent change in disposable income (per capita) asthe only independent variable would provide the most accurate forecast. Listed below are the Adjusted R2 values for three regression models. Based on these values, and keeping in mind that the ticket holders are only concerned about forecasting, what is the correct conclusion?
- NFL Attendance vs. US Population and Percent Change in Disposable Income.
Adjusted R2= 0.8964 - NFL Attendance vs. US Population: Adjusted R2= 0.8609 - NFL Attendance vs. Percent Change in Disposable Income. Adjusted R2= -0.0244
