Chapter 12.A.2, Problem 1Q

Suppose an experimenter has taken three independent measurements on each of five treatment levels and intends to use the analysis of variance to test

H 0 : μ 1 = μ 2 = μ 3 = μ 4 = μ 5 ( = 0 )

versus

H 1 : not all the μ j s are equal

Two of the possible alternatives in H 1 are

H 1 * : μ 1 = 1 , μ 2 = 2 , μ 3 = 0 , μ 4 = 1 , μ 5 = 2

And

H 1 * * : μ 1 = 3 , μ 2 = 2 , μ 3 = 1 , μ 4 = 0 , μ 5 = 0

Against which alternative will the F test have the greater power? Explain.

Consider the state space model X₁ = §Xt−1 + Wt, Yt = AX+Vt, where Xt Є R4 and Y E R². Suppose we know the covariance matrices for Wt and Vt. How many unknown parameters are there in the model?
Business Discuss
You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker.  Based on previous evidence, you believe approximately p∗=11% of the population have the genetic marker.  You would like to be 90% confident that your estimate is within 0.5% of the true population proportion.  How large of a sample size is required?n =       (Wrong: 10,603) Do not round mid-calculation. However, you may use a critical value accurate to three decimal places.
