Chapter , Problem 9(choose chapter or problem)
Critical Thinking Suppose we have a binomial distribution with n trials and probability of success p. The random variable r is the number of successes in the n trials, and the random variable representing the proportion of successes is p r/n. (a) n 50; p 0.22; Compute P(0.20 p 0.25). (b) n 38; p 0.27; Compute the probability that p will equal or exceed 0.35. (c) n 51; p 0.05; Can we approximate p by a normal distribution? Explain.
