The faculty at a large university wanted to know what proportion of the students

Question

The faculty at a large university wanted to know what proportion of the students at the university thought foreign language classes should be required. The statistics department offered to cooperate in conducting a survey, and a simple random sample of 500 students was selected from all the students enrolled in statistics classes. A survey form was sent by email to these 500 students. Which statement is true about this study? The sample is not random because students who like math do not necessarily like foreign language. Since the sample is random, it is representative of the population of interest. The sample is biased because students who like math are better at foreign languages. Even though the sample is random, it is not representative of the population of interest.

Explanation / Answer

The answer is option D. The sample is random. However this sample isnot representative of the entire population of the university because the likes of the students enrolled in statistics will not necessarily match the likes of students enrolled in other subjects.
