Question

A study 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.
Select the correct explanation of the reason for the bias observed in responses to the survey.
The drivers showed a response bias since they may report they always use seatbelts even if they do not.
The sample population is more affluent than the average since they all have cars.
The drivers were not selected at random.
The drivers were biased towards using seat belts.
Do you expect bias in the same direction in most surveys about seat belt use?
