There must be k simple random samples, one from each of k populations or a randomized experiment with k treatments. B. The populations must have the same variance; that is, each treatment group has population variance sigmaσ2. C. The within-sample variability must be less than the combined variances of each group. D. The k samples must be independent of each other; that is, the subjects in one group cannot be related in any way to subjects in a second group. E. The sample means must all be equal. F. The populations must be normally distributed.
