Question
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. Consider a random sample of 
1600
 people who have stopped using the painkiller.
  1. Find the mean of 
    p
    , where 
    p
     is the proportion of people in the sample who experience withdrawal symptoms.
  2. Find the standard deviation of 
    p
    .
  3. Compute an approximation for 
    P<p0.015
    , which is the probability that fewer than 
    1.5%
     of those sampled experience withdrawal symptoms. Round your answer to four decimal places.
(If necessary, consult a list of formulas.)
