A professor wanted to determine the proportion of students in his class who have cheated on an exam. The professor selects a ran
dom sample of 30 students from his class and emails them the question "Have you ever cheated on an exam?". He receives responses from 10 of the 30 students. Which of the following statements are true? Select all that apply.
Select one or more:
a. This study would suffer from undercoverage because the professor should have selected a sample from the entire student body of the university.
b. This study suffers from non-response bias because only 33% of the people surveyed provided a response.
c. This study suffers from response bias since students will not want to tell a professor whether or not they have cheated.
d. The study should not suffer from any bias since it was based on a random sample.
