Astudy in el paso, texas, looked at seat belt use by drivers. drivers were observed at randomly chosen convenience stores. after they left their cars, they were invited to answer questions that included questions about seat belt use. in all, 75% said they always used seat belts, yet only 61.5% were wearing seat belts when they pulled into the store parking lots.
explain the reason for the bias observed in responses to the survey. do you expect bias in the same direction in most surveys about seat belt use?
