Suppose that in the population, exactly 56% of all households own at least one pet. If we take many simple random samples of 1000 households from this population, the sample proportion who own at least one pet will vary from sample to sample. The sampling distribution of the sample proportion would be close to Normal and would have a center equal to what value? A 0.0157 B 0.0316 C 0.0002 D 0.0056 E 0.5600
