Question
A sportswriter wants to know how strongly all Lafayette residents support the local minor league baseball team, the Lafayette Leopards. She stands outside the stadium before a game and interviews the first 20 people who enter the stadium. The newspaper asks you to comment on their survey of local opinion. You say: - a) This is a simple random sample. It gives very accurate results. - b) This is a convenience sample. It will almost certainly overestimate the level of support among all Lafayette residents based on the location picked. - c) This is a census, because all fans had a chance to be asked. It gives very accurate results. - d) This is a simple random sample. The results are not biased, but the sample is too small to have high precision.
