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. Also given are the products of the player payroll values and mean attendance values for each of the sixteen teams. (These products, written in the column labelled " xy ," may aid in calculations.)
