a. Suppose that a two-way ANOVA is to be performed, with 1995 starting salary as the dependent variable and with school type (SCHOOL) and reputation rank among academics (REP1 = 1 if reputation rank is in the top 10; = 2 if rank is 11 to 20; = 3 if rank is 21 or worse) as the two factors. State precisely the ANOVA model. Are the factors fixed or random?
b. In the SAS output that follows, complete the ANOVA table.
c. Analyze the data to determine whether there are significant main effects due to school type and reputation rank and whether these factors significantly interact.
