Withdrawal symptoms may occur when a person using a painkiller stops using it. For a certain, widely taken painkiller, withdrawal symptoms occur in 14% ofpeople who have stopped using the painkiller. Suppose that we will take a random sample of 8 people who have stopped using the painkiller. Let p represent theproportion of people from the sample who experienced withdrawal symptoms. Consider the sampling distribution of the sample proportion p.Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed.(a) Find la (the mean of the sampling distribution of the sample proportion).Ha = ](b) Find on (the standard deviation of the sampling distribution of the sample proportion).

Recent studies have shown that about 16% of American adults fit the medical definition of being obese. A large medical clinic would like to estimate what percentage of their patients are obese, so they take a random sample of 400 patients and find that 52 are obese. Suppose that in truth, the same percentage holds for the patients of the medical clinic as for the general population, 16%. Find the mean of the sampling distribution of p̂.
