a study of the fuel economy for various automobiles plotted the fuel consumption (in liters of gasoline used per 100 kilometers traveled) vs. speed (in kilometers per hour). a least squares line was fit to the data. here is the residual plot from this least squares fit. what does the pattern of the residuals tell you about the linear model? (a) the evidence is inconclusive. (b) the residual plot confirms the linearity of the fuel economy data. (c) the residual plot does not confirm the linearity of the data. (d) the residual plot clearly contradicts the linearity of the data. (e) none of the above
