Webb(a) Construct a normal probability plot of the residuals. Does there seem to be any problem with the normality assumption? (b) Construct and interpret a plot of the residuals versus the predicted response. (c) Plote the residuals versus team passing yardage x 2. Does this plot indicate that the model will be improved by adding x 2 to the model? 2. WebbplotResidualDistribution(resultsObj) shows the normal probability plot and the corresponding histogram of the residuals. Use the plot to check if the distribution of the residuals deviates from the normality.
