- Help please!arrow_forwardYou 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?arrow_forwardHelp please!arrow_forward

- What does a coefficient of correlation of 0.70 infer?arrow_forwardPlease give an example of an IMPOSSIBLE correlation coefficient.arrow_forwardWhat does a correlation coefficient of 2 indicate? There is a weak relationship between the two quantitative variables. It indicates a calculation error, as the correlation coefficient cannot be 2. There is a strong relationship between the two quantitative variables. It indicates a non-linear relationship between the two quantitative variables. There is no linear relationship between the two quantitative variables.arrow_forward
