A statistics practictioner conduct a two-factor analysis of variance experiment with a=4 b=3 and r=8, the sums of squares are listed here: SS(T)=9420 SS(A)=203 SS(B)=859 SS(AB)=513 (a) Test at 5% significance level to determine whether factors A and B interact? (b) Test at 5% significance level to determine whether differences exist between the levels of factors A? (c) Test at 5% significance level to determine whether differences exist between the levels of factors A?

Two men, A and B, who usually commute to work together decide to conduct an experiment to see whether one route is faster than the other. The men feel that their driving habits are approximately the same, so each morning for two weeks one driver is assigned to route I and the other to route II. The times, recorded to the nearest minute, are shown in the following table. Using this data, find the 90% confidence interval for the true...
