Withdrawal symptoms may occur when a person using a painkiller suddenly stops using it. For a special type of painkiller, withdrawal symptoms occur in 5% of the cases. Consider a random sample of 1900 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 P6>0.04), which is the probability that more than 4% of those sampled experience withdrawal symptoms. Round your answer to four decimal places.

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
5% of the cases. Consider a random sample of 1900 people who have stopped 00
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>0.04), which is the
probability that more than 4% of those sampled
experience withdrawal symptoms. Round your answer
to four decimal places.

In a previous research project for University of Michigan, you wanted to know what extent students were a morning person. Using a scale from 1 (not a morning person) to 7 (very much a morning person), you had a mean of 3.40 and a standard deviation of 1.47.

Use z scores to compare the given values. The tallest living man at one time had a height of 225 cm. The shortest living man at that time had a height of 104.3 cm. Heights of men at that time had a mean of 173.55 cm and a standard deviation of 5.15 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= and the z score for the shortest man is z= the V man had the height that was more extreme. (Round to two decimal places.)
