The population means for each of four populations is 100, and the variance for each of the four populations is 16. The four ns for samples drawn from each population all equal 50. (When you answer the question, do not calculate-just think.) In a one-way ANOVA, what is the expected value of MS_B? A) 0 B) 4 C) 16 D) 100

The expected value of MS_B in a one-way ANOVA can be calculated using the formula E(MSS) = (n-1) * σ^2, where n is the sample size and σ^2 is the population variance. Thus, E(MS_B) = (4-1) * 16 = 48. This is also known as the between-groups mean square (MSB).
