Congressmen Gerry Studds (a Massachusetts Democrat) and Daniel Crane (an Illinois Republican) were both censured by the House of Representatives for having had sex with teenage pages. A questionnaire in the Cape Cod Times asked readers whether Studds should “resign immediately,” “serve out his present term, and not run for reelection,” or “serve out his present term, run for reelection” [31]. Out of a Sunday circulation of 51,000 people, 2,770 returned this questionnaire:

a. Explain why there might be sampling bias in this study.

b. If a true random sample had been conducted, which of these four percentages would you expect to be higher than in this newspaper survey?
