MA 17 Is there a relationship between the raises administrators at State University receive and their performance on the job? A faculty group wants to determine whether job rating (x) is a useful linear predictor of raise (y). Using the method of least squares, the faculty group obtained the following prediction equation, y = 14, 000 + 2, 000x. Interpret the estimated y-intercept of the line The base administrator raise at State University is $14,000. There is no practical interpretation, since rating of O is nonsensical and outside the range of the sample data. For an administrator who receives a rating of zero, we estimate his or her raise to be $14,000. For a 1-point increase in an administrator's rating, we estimate the administrator's raise to increase $14,000
