# Question

Consider an election poll designed so that each household has an equal chance of being selected and one registered voter is interviewed from each selected household. Analyze what would happen if single-voter households were more likely to vote Democratic than households containing more than one registered voter. In particular: Would the “percent voting Democrat in the sample” be an unbiased estimator for the percent of all registered voters? If not, would it overestimate or underestimate this true percentage?
