# Question

In a study of five populations with five equal sample sizes of ni = 20, the 100 data values produced a mean square within samples of s2W = 0. Without having access to the 100 data values, answer the following questions about the sample means and the residuals?

a. Are the five sample means equal?

b. What can be concluded about the 100 sample residuals: eij = yij –yi?

a. Are the five sample means equal?

b. What can be concluded about the 100 sample residuals: eij = yij –yi?
