See the table for data on the ratings of quarterbacks for the 2008 National Football League season (The Sports Network).
Round your answers to two decimal places (e.g. 98.76).
Assuming that a simple linear regression model is appropriate, fit the regression model relating the rating (y) to the average number of yards gained per pass attempt (x).
Round your answers to two decimal places (e.g. 98.76).
