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?

There are two stocks in your portfolio. Stock Weight E(r)
Variance A 1/3 9% 0.0036 B 2/3 15% 0.0081 a) Assume stock A and B
are perfectly positively correlated, calculate the risk and return
for your portfolio. b) Repeat (a), assume the correlation is 0. Why
is the risk now lower than in (a)?

Consider an experiment with four independent variables: A, B, C,
and D.
Factor A has 3 levels and is a between-subjects variable; Factor
B has 2 levels and is a within-subjects variable; Factor C has 2
levels and is a between-subjects variable; Factor D has 3 levels
and is a within-subjects variable.

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...
