Answer

# Brief Explanations: The researcher is questioning students as they leave a university dorm. This is convenience sampling since the selection is based on the ease of access (the location of the dorm). There is potential bias as students in the dorm may have different eating - habits compared to students who live off - campus. For example, dorm students may be more likely to use the campus dining facilities, and this sample may not represent the entire student body's eating habits. # Answer: E. Convenience sampling is used, because students are chosen due to convenience of location.
