(See Exercise 2.4ㅁㅁ, p. 48) In a random sample of 500 US adults, let p^ represent the proportion who are "cord cutters." a. Find the mean of the sampling distribution of p^ b. Find the standard deviation of the sampling distribution of p^. c. What does the Central Limit Theorem say about the shape of the sampling distribution of p^? d. Compute the probability that p^ is less than .17. e. Compute the probability that p^ is greater than 15.
