Unformatted text preview: 2 { Y .jY .j } . Question 2: For the model in Question 1, we can show that E { SSTR } = σ 2 ( r1) + s r X j =1 α 2 i . (a) Suppose that we are considered with the power for the test for A main effects. Suppose that σ = 10 . 5 and that we would like to detect a range in the A 1 main eﬀects of Δ = 20 units with high probability. Give the value of the noncentrality parameter for the corresponding noncentral F distribution. (b) Refer to part (a), if α = 5%, the power of the test is the probability of which event? 2...
