2. The article "Should Pregnant Women Move? Linking Risks for Birth Defects with Proximity to Toxic Waste Sites" (Chance (1992): 40-45) reported that in a large study carried out in the state of New York, approximately 30% of the population lived within I mile of a hazardous waste site. If an SRS of 400 pregnant women is selected, how likely is it that the sample proportion will be within 5% of the true population proportion? Would this probability be larger or smaller if we selected an SRS of size 500? (You don't need to do a calculation to figure this out...use common sense!)
