For a special type of painkiller, withdrawal symptoms occur in 2% of the cases, Consider a random sample of 1600 people who have stopped using the painkiller. Answer the following. (If necessary, consult a list of formulas.) (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 <0.01), which is the probability that fewer than 1% of those sampled experience withdrawal symptoms. Round your answer to four decimal places.
