The variance for every random variable for both groups is the same. Which cases will produce the highest probability that the sample mean of group A (TA) is larger than the sample mean of group B (B), i.e. largest value of P(ïA > ¤B)? A. The variance is 40 and 8 variables in each group. B. The variance is 20 and 2 variables in each group. C. The variance is 10 and 4 variables in each group. D. A will never be larger than B E. TA will always be larger than TB
