Consider the hypothesis: H0 :μ=μ0 Ha :μ̸=μ0 where σ2 is known. It is known that for detecting a true mean of μ1 ̸= μ0 with probability 1 − β and type I error α, the required sample size is approximately: n ≈ [(Zα/2 + Zβ )σ/δ]^2 (a) Let us consider that μ0 = 15 and σ2 = 9. If the true mean is 20, what sample size must be used to ensure that the probability of type II error is no greater than 0.10? Assume that α = 0.05. (b) Derive the expression for n in 7(a).
