For major league baseball teams, is there a relationship between player payrolls and gate money? Here are data for each of the American 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. Also given is the product of the player payroll and the mean attendance for each of the fourteen teams. (These products, written in the column labelled "xy", may aid in calculations.) Player Mean payroll, x attendance, y (in $1,000,000 (in xy s) thousands) 45- Anaheim 59.2 25.56 1513.152 40- Baltimore 80.5 40.74 3279.57 35- Boston 97.0 31.98 3102.06 30- Chicago White Sox 42.3 24.07 1018.161 25- Mean attendance (in thousands) Cleveland 90.5 42.72 3866.16 20- Detroit 68.6 31.23 2142.378 Kansas City 31.8 20.74 659.532 10- Minnesota 23.5 13.09 307.615 New York Yankees 114.3 39.88 4558.284 80 Oakland 43.0 21.36 918.48 20 100 120 140 Seattle 69.9 38.89 2718.411 Player payroll Tampa Bay 65.2 18.27 1191.204 (in $1,000,000s) Texas 72.7 34.57 2513.239 Figure 1 Toronto 56.8 22.47 1500.996 Send data to calculator VWhat is the slope of the least-squares regression line for these data?
