Question 9)Does the residual plot give any suggestion that one of the… 9)Does the residual plot give any suggestion that one of the assumptions of the regression model may be violated?  If not, why not?  If so, which of the assumptions may be violated, and what in the residual plot indicates this.Group of answer choicesa)I would not say that the residual plot gives indication that any assumptions are violated. The residual plots look random, the errors add up to 0, and the points look independent from other points.  b)Since there are not many data points, it is hard to tell. c)The residual plot above does not give any suggestion that one of theassumptions of the regression model has been violated.To begin with,the plots indicate linearity, with only two outliers that do notsignificantly affect the linear relationship. The model has only oneindependent variable thus no multicollinearity and multivariatenormality. It can also be noted that the residuals are independent from each other hence no autocorrelation. Lastly, the data on the scatter plot are homoscedastic that is the variances are seen to be homogeneous. d)Moving from left to right, the residual plot seems to fan out.  This suggests that there is more variation in price among the vans with higher predicted prices (lower mileage) than among those with lower predicted prices.  This would be a violation of the “constant variance” assumption.   YearAgeMileage (1000s)Price (1000s)Type (full camper/MV)200096430FC2000982.34528MV1997125927FC2001876.76724.9MV2001869.21821.992MV2002788.27519.988MV199514108.07715FC20009110.60813.995MV2001881.71810.999MV20009129.5918.888MV Math Statistics and Probability MATH 244 Share QuestionEmailCopy link Comments (0)
