18. As a part of a study on student transportation options, the school board emails a survey to
every high school student in the district. The email is sent to 15,000 students, and the board
receives almost 8,000 survey responses. One of the questions on the survey is "Do you have a
driver's license?" Based on the survey, the Board concludes that 85.4% of students of legal
driving age have a driver's license. Is there a problem with the school board's estimate? If so,
what is the problem?
(1 point)
O There is no problem with the school board's estimate. The study was well conducted, and the sample
size is large, so the estimate will be accurate.
O There is a problem. This is a volunteer survey, so the estimate cannot be relied upon to represent the
population of students.
O There is a problem. The study did not have a control, so there is no way to tell if the estimate is accurate
or not.
O There is a problem. The question asked is a leading question, so the results of the survey will be biased
and unreliable.
