7.Assume an experiment using randomized block design has four treatments and nine blocks, for a total of 4 9 = 36 observations. Assuming the Total Sum of Squares for the responses is SS(Total) = 500 and= .05, test the null hypothesis that the treatment means are equal when the Sum of Squares for Treatments (SST) is 40% of SS(Total) and the Sum of Squares for Blocks (SSB) is 40% of SS(Total).

A.F= 16.00

B.F= 22.00

C.F= 18.00

D.F= 12.88

9.Independent random samples of 800 observations each are selected from two binomial populations. The sample from population 1 produced 320 successes and the sample from population 2 produced 400 successes. TestH0: (p1- p2) = 0 againstH: (p1- p2) 0 using= .01.

A.z= -4.16

B.z= -4.02

C.z= -4.68

D.z= -3.96

11.When= .10, what is the rejection region that should be used to testagainst? Assumev1= 10 andv2= 12.

A.F > 2.33

B.F > 2.04

C.F > 1.74

D.F > 2.78
