Withdrawal symptoms may occur when a person using a painkiller suddenly stops using it. For a special type of painkiller, withdrawal symptoms occur in 1% of the cases. A random sample of 1100 people who have stopped using the painkiller is going to be taken. Let p be the proportion of people in the sample who experience withdrawal symptoms. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. X (b) Find the standard deviation of p. (c) Compute an approximation for P (p > 0.02), which is the probability that more than 2% of the people in the sample experience withdrawal symptoms. Round your answer to four decimal places
