Answer true or false to the following statements and explain your answers. a. In a multiple linear regression analysis, a data point with a large standardized residual should be removed from the data set, and the regression equation should be recalculated. b. In a multiple linear regression analysis, if a plot of the residuals against a predictor variable shows curvature, the normality assumption for regression inferences is violated.
