For major league baseball teams, do higher player payrolls mean more
gate money? Here are data for each of the American League teams in
the year 2002. The variable x denotes the player payroll (in millions of
dollars) for the year 2002, and the variable y denotes the mean
attendance (in thousands of fans) for the 81 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 is î=11.43 +0.23x.
