For major league baseball teams, is there a relationship between player payrolls and gate money? Here are data for each of the National League teams for the year 2000. The variable x denotes the 2000 player payroll (in millions of dollars), 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. Player payroll, x (in $1,000,000s) Mean attendance, y (in thousands) 45- Arizona Atlanta 87.0 34.81 94.5 39.88 40- Chicago Cubs Cincinnati Colorado Florida 65.3 34.44 35- 52.6 31.85 30 64.8 40.74 25+ 30.9 15.06 Houston 58.3 37.78 Los Angeles 105.0 37.16 Milwaukee 41.5 19.38 10- Montreal 39.5 11.48 34.81 New York Mets Philadelphia Pittsburgh San Diego San Francisco 99.8 20 100 140 53.9 19.88 36.3 21.60 Player payroll (in $1.000,000s) 64.1 29.88 Figure 1 59.6 40.99 St Louis 80.7 41.23 The least-squares regression line for these data has a slope of approximately 0.31.
