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

    Suppose that in the population, exactly 41% of all adults make a wish when they blow out candles on a birthday cake. If we select many random samples of size n = 400 people from this population, we know the sample proportion who make a wish when blowing out candles on a birthday cake will vary from sample to sample. The sampling distribution of the sample proportion would be Normal in shape and would have a standard deviation equal to...
