Annual Income. Refer to Problem 18. OutputsA.22(a), (b), and (c) on page A-62 display, respectively, plots of residuals against education, residuals against age, and residuals against predicted income; Output A.22(d) shows a normal probability plot of the residuals. Do these graphs suggest any violations of the assumptions for multiple linear regression inferences for the variables under consideration?
