A major university decides to survey the student body to find out their opinion about life on campus. All students are identified by their major field of study, such as education, mathematics, or literature. The university randomly chooses four of the eight majors offered at the university. The university sends the survey to a random sample of the students in these four majors. Identify the sampling method used (convenience, systematic, stratified, or voluntary-response).
