A university is subdivided into faculties of Arts, Engineering, Humanities, Law and Science. The numbers of students in these faculties are 1300, 800, 1100, 500 and 1400 respectively. A questionnaire concerning library usage is sent to all the students. The first 300 replies opened contained 101 from Arts students, 30 from Engineering students and 69, 17 and 83 from students of the other three faculties respectively. Using a 0.1% significance level, test whether the replies appear to be providing an unbiased representation of the students in the university.
