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.
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 20.3 pounds and a standard deviation of 3.7 pounds.
