Withdrawal symptoms may occur when a person using a painkiller suddenly stops using it. For a special type of painkiller, withdrawal symptoms occur in  4%of the cases. Consider a random sample of 2400 people who have stopped using the painkiller.   Answer the following:   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>0.05), which is the probability that more than 5% of those sampled experience withdrawal symptoms. Round your answer to four decimal
