Problem 8.59 Let X be the sample total from a random sample of size n = 15 taken from a Bernoulli distribution with parameter p. To test H0 : p = 0.90 against H1 : p < 0.90, we choose the rejection region C = {x : x 0.4. Consider the following test: A random sample of 15 patients are given the drug, and the number of recoveries is denoted by X. The null hypothesis will be rejected if X > 8, i.e., accept H0 if X ≤ 8 reject H0 if X > 8.
