WebSep 3, 2024 · Let the rejection region be R = { ( X 1,.., X n): 1 n ∑ i X i > c }. Find c so that the test has size α. Then find the power of the test under H 1, i.e. power (1). My attempt: For … WebDefinition 13. The power function of a hypothesis test with a rejection region R is a function of θ defined by β ( θ) = Pθ ( X ∈ R ). A good test should have a power function close to 0 for all θ ∈ Θ 0 and 1 for all so that both type I and type II errors are low.

Definition of Rejection Region For Chi Square Test Chegg.com

WebI can come up with two different ways to determine the rejection region: { T ( x) − μ > c }. μ is the mean of the distribution F of T ( X) under null, and c is determined by solving inf c ≥ 0 c subject to P T ( X) ∼ F ( T ( X) − μ > c) ≤ α. So the rejection region is symmetric around μ. WebRejection Region For Chi Square Test. Rejection region is considered as the crucial part of the testing process. For the hypothesis testing, the researcher, first, collects the sample data and the next step is to determine the test statistic. For example, consider a case of rejection region in the chi-square test.
