) Consider we are interested in determining if the proportion of individuals with a nonhereditary genetic mutation is less than 0.35. Suppose we collect a sample of 20 independent individuals. We will consider the following hypothesis, Ho:p = 0.35 HA:p < 0.35 with a rejection region of RR = p < 0.25. a) Is the sample size large enough for the normal approximation to be valid? Explain your reasoning. a) Calculate the type I error a. b) Calculate the type Il error B when p = .125.
