The production of wine is a multi-billion-dollar worldwide industry. In an attempt to develop a model of wine quality as judged by wine experts, data was collected from red wine variants from a particular type of foreign wine. The multiple linear regression model Y; = 3.285 + 0.429X1; - 24.911X2; was developed from a sample of 20 wines, where Y, is the wine quality, measured on a scale from 0 (very bad) to 10 (excellent) based on the alcohol content (%), X1;, and the amount of chlorides, X2j. Use the regression model and the accompanying data to complete parts (a) through (e) below.\fa. Plot the residuals versus Y . Choose the correct graph below. O A. OB. O C.

O B. O c. O D. 4- Residuals 4- O- Residuals Residuals . . -41 Residuals 0.2 X2 0.2 X2 0.2 -4- X2 0.2 X2d. In the residuals plots created in parts (a) through (c), is there any evidence of a violation of the regression assumptions? 0 A. No, because the residuals appear randomly distributed in all the plots. 0 B. Yes, because the residuals appear randomly distributed in all the plots. 0 C. Yes. because there appears to be a pattern in at least one of the residual plots. O D. No, because there appears to be a pattern in at least one of the residual plots. 9. Should you compute the Durbin-Watson statistic for these data? Explain O A. Yes, because there is no indication that the data were collected in a specic time order. O B. No, because the data were collected in a specic timeorder, so the DurbinWatson test statistic should not be computed. O C. No, because there is no indication that the data were collected in a specic time order. 0 D. Yes, because the data were collected in a specic timeorder, so the Durbin-Watson test statistic should be computed
