Question

In order to estimate the proportion of students that text while driving, a school administrator selects a simple random sample of students from a list of all students at the school who have parking permits. The students are called to the office, one at a time. The administrator asks each student, “Do you text while driving, even though you are not supposed to?” Based on the survey, the administrator estimates that only 2% of students with parking passes text while driving. What potential bias is present in the design of this survey and what is the likely direction of the bias?

(A) The sample proportion is likely an underestimate of the population proportion due to response bias.
(B) The sample proportion is likely an underestimate of the population proportion due to undercoverage.
(C) The sample proportion is likely an underestimate of the population proportion due to nonresponse.
(D) The sample proportion is likely an overestimate of the population proportion due to response bias.
(E) The sample proportion is likely an overestimate of the population proportion due to undercoverage.
