Critical region binomial distribution

WebJan 10, 2024 · 1 For a binomial distribution, the hypothesis H 0: p = 0.2 and H 1: p ≠ 0.2 are tested at the 10 level. 20 trials are performed and the critical region is X = 0 or X > 7 . Calculate the probability of a type II error and the power when the true value of p is 0.3: My workings: X − B ( 20, 0.3) WebNov 23, 2024 · is a rejection region for the likelihood ratio test for the p parameter of a binomial distribution, where, Next, I am asked to show that the above rejection region can be simplified in a way that doesn't involve the log function, using the symmetry property of the LHS function. I have tried plotting the chart, and indeed it is a symmetric function.

WebJun 3, 2024 · Find the critical region for a hypothesis test using a 5 % significance level. I have found P ( X = 0) = 0.0038 P ( X ≤ 1) = 0.0274 P ( X ≥ 9) = 0.0468 P ( X ≥ 10) = 0.0173 I therefore said that the critical region is X = 0 and X ≥ 10, because we require the … WebAug 30, 2024 · A critical region doesn't really "go with" a p-value; you choose your critical region before you see data, while the p-value is a function of the data. If you choose your critical region after the fact you're asking for people to accuse you of p-hacking. As you've discovered, it's easy to identify a p-value without having a critical region! connecting an xbox controller to laptop https://axiomwm.com
