How do you find the rejection region
WebIn the previous example for Penn State students, we found that assuming the true population proportion is 0.5, a sample proportion of 0.556 is 2.504 standard 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.

My attempts: Set T ( X) = X 1 + … + X n, so that T ∼ B i n o m i a l ( n, p). Suppose D = { X: T ( X) > c, c ∈ N, 0 ≤ c ≤ n − 1 } is the region of rejection, and let ϕ be the characteristic function of D. The power function then is WebFind the Rejection Region. A drug claims to lower the blood pressure (by at least 10 mmHg) in 30% of all patients. A random sample taken shows a significant drop in blood pressure for only 20% of patients (n =35). Test the original claim using a one-sided test at the 1% significance level. I was attempting a past paper and this question came up ...
