Which of the following statements is supported by these plots? (a) There is no striking evidence that the assumptions for regression inference are violated. (b) The abundance of outliers and influential observations in the plots means that the assumptions for regression are clearly violated. (c) These plots contain dramatic evidence that the standard deviation of the response about the true regression line is not approximately the same for each x-value. (d) These plots call into question the validity of the assumption that the later ratings vary Normally about the least-squares line for each value of the initial ratings. (e) A linear model isnt appropriate here because the residual plot shows no association. AP4
