What is the correlation coefficient for this data set?

Use table of critical values for correlation coefficient.

What does the square of the linear correlation coefficient measure (rxr)?

You are a data analyst for the MLB and your boss asks you to analyze data related to stadium attendance and winning percentage. You obtain data on 30 MLB teams (see the data file for this project; this data is from the early 2000’s, so the teams might not reflect the current state). The file includes the cost of the team name, league, year the park was built, stadium capacity, average attendance, and winning percentage. You decide to calculate the correlation coefficient to see if the winning percentage and average attendance are related, and then the least squares regression line, in order to predict the winning percentage of a team whose average attendance is 65000.    What to do: Prepare your summary of results, and make sure you include (1) the correlation and (2) an equation for predicting the winning percentage based on average attendance. What is (3) the expected winning percentage of a team whose average attendance is 65000? Does this seem reasonable?
