In 2012 , the total payroll for the New York Yankees was almost \$200 million, while the total payroll for the Oakland Athletics (a team known for using baseball analytics or sabermetrics) was about $55 million, less than one-third of the Yankees' payroll. In the following table, you will see the payrolls (in millions) and the total number of victories for the baseball teams in the American League in the 2021 season. Answer the following questions. For all three questions, show computation by showing all the computational steps. Do NOT use the Excel Regression function. (a) Develop a regression model to predict the total number of victories based on the payroll. (b) Use the model to predict the number of victories for a team with a payroll of $79 million. (c) Suppose SST 1560, SSR=1250. What is the value of r2? Explain it in the context of this problem. What is the value of correlation coefficient between these two variables? Must retain all the formulas in the worksheet. If I cannot verify the formulas used and see static results only, a minimum 50% penalty will be applied
