a)F > 3.81
b)F > 3.63
c)F > 3.24
d)F > 4.08
QUESTION 2

6. Below is a one-way ANOVA model for comparing three treatments with ni patients receiving treatment i, i 1, 2, 3. Let Yij denote the response of the jth patient receiving the ith treatment, u be the overall mean response, ai the treatment effect and eij the error term. Then, Yg=u a+Eij where, i 1, 2, 3 and j 1,... depends on the subscripts i and j, ni with nl 25, n2 - 30 and n3 20. The response 5if...

Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
