A recent Gallup Poll interviewed a random sample of 1,523 adults. Of these, 868 bought a lottery ticket in the past year. Suppose that, in fact, (unknown to Gallup) exactly 60% of all adults bought a lottery ticket in the past year. If Gallup took many SRSs of 1,523 adults, the sample proportion who bought a ticket would vary from sample to sample. The sampling distribution would be close to normal with O mean 0.6 and standard deviation 0.00016 mean 0.6 and standard deviation 0.0126 mean 0.6 and standard deviation 0.4899 mean 0.6 and standard deviation 0.0251
