ANOVA: Mean squares and the common population variance
In an effort to counteract student cheating, the professor of a large
class created four versions of a midterm exam, distributing the four
versions among the 344 students in the class, so that each version was
given to 86 students. After the exam, the professor computed the

Group sample size sample
mean sample varience
Version A 86
Version B 86 155.9
