E O REGRESSION AND CORRELATION Computing the sample correlation... Kelly v V 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 2001. The variable x denotes the 2001 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 Mean (in $1,000,000 attendance, y s) (in thousands) Anaheim 46.6 24.69 Baltimore 73.4 38.15 45- X Boston 109.6 32.47 40 - X X Chicago White 35 _ Y 62.4 Sox 21.85 X 30 Cleveland 92.0 39.26 X 25.

Answer the following. Carry your intermediate computations to at least four decimal places, and round your answers as specified below. (If necessary, consult a list of formulas.) What is the value of the y-intercept of the least-squares regression line for these data? Round your answer to at least two decimal places. What is the value of the sample correlation coefficient for these data? Round your answer to at least three decimal places. X 5
