From text (3rd ed in parentheses): Chapter 11, Q 4(4), 6(6), 14(13), 16(14), 48(42), 50(44). You should SAS for questions 16, 48 and 50. If you use proc glm rather than proc anova (with all the rest of the code the same) then you may add an output statement (see the multiple regression example on the web) to get the residuals and use proc univariate to plot them and proc print to print them. Data are available for question 48 but I want to see you enter the data for question 50 and question 16 yourselves.
