For major league baseball teams, do higher player payrolls mean more gate money? Here are data for each of the National League teams in the yearÂ
. The variableÂ
 denotes the player payroll (in millions of dollars) for the yearÂ
, and the variableÂ
 denotes the mean attendance (in thousands of fans) for theÂ
home games that year. The data are plotted in the Figure 1 scatter plot, as is the least-squares regression line. The equation for this line isÂ
 .
