Web1. 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. Web4 nov. 2016 · 1. I have got one problem as following. There are two coins in a box (that look very much the same). For one coin, the probability of heads is 0.7 and for the other, the probability of heads is 0.1. You will randomly select one of the coins and toss it once. Based on the result of this toss, you will decide which coin you have tossed.

WebThe test power is the probability to reject the null assumption, H 0, when it is not correct. Power = 1- β. Researchers usually use the power of 0.8 which means the Beta level (β), the maximum probability of type II error, failure to reject an incorrect H 0, is 0.2. 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 < z α 2 μ) = P ( μ 0 − z α 2 σ n ≤ X ¯ ≤ μ 0 + z α 2 σ n) = Φ ( z α 2 + μ 0 − μ σ / n) − Φ ( − z α 2 + μ 0 − μ σ / n).
