(a) Find the mean of p, where p is the proportion of people in the sample who experience withdrawal symptoms. (b) Find the standard deviation of p. (c) Compute an approximation for P(p <0.04), which is the probability that fewer than 4% of those sampled experience withdrawal symptoms. Round your answer to four decimal places.
