Withdrawal symptoms may occur when a person using a painkiller suddenly stops using it. For a special type of painkiller, withdrawal symptoms occur in 2% of the cases. A random sample of 1600 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 0 2 CS Scanned with CamScanner dla do 10363 h (b) Find the standard deviation of pi 0 (Compute an approximation for P-0015), which is the probability that more than 1.5% of the people in the sample experience withdrawal symptoms Round your answer to four decimal places,
