Course : Analysis of experience plans MAT3378 Exercise:

(A) A balanced factor study is planned with 5 groups.

We want to detect a difference between the averages with a probability of 80% if the average quadratic effect is f = 0.5. Assuming the balanced plan.

Determine the number of observations required per group.
