Web1 Answer. We want to find the probability of not rejecting the null hypothesis, given that the alternate hypothesis λ = 2 is true. This is the probability that the value of the test statistic, in this case a Poisson random variable with mean 2, takes on value 0, 1, or 2. Now we need to make a standard Poisson λ = 2 calculation. WebProviding the solution: β ( μ) = P ( type II error) = P ( accept H 0 μ) = P ( X ¯ − μ 0 σ / n < z α 2 μ). If X i ∼ N ( μ, σ 2), then X ¯ ∼ N ( μ, σ 2 n). Thus, β ( μ) = P ( X ¯ − μ 0 σ / n …
