Chapter 0, Problem 24.45(choose chapter or problem)
(a) Find the mean and standard deviation of the standardized residuals. Why doyou expect values close to those you obtain?(b) Make a stemplot of the standardized residuals. Are there any strikingdeviations from Normality? The most extreme residual is z = 1.99. Would thisbe surprisingly large if the 23 observations had a Normal distribution? Explainyour answer.(c) Plot the standardized residuals against the explanatory variable. Are thereany suspicious patterns?
