Consider an ANOVA situation with a = 5 treatments. Let 2 = 9 and a = 0.05,

Question:

Consider an ANOVA situation with a = 5 treatments. Let σ2 = 9 and a = 0.05, and suppose that n = 4.
(a) Find the power of the ANOVA F-test when μ1 = μ2 = μ3 = 1, μ4 = 3, and μ5 = 2.
(b) What sample size is required if we want the power of the F-test in this situation to be at least 0.90?
