The university administrator wants a quick estimate of the average course size, i.e. how many students are enrolled in one course on average. However, since he does not want the faculty to find out about his interest, he has decided to use the students as his help. He has decided to randomly select 100 students to find out and report to him the number or numbers of students in his course or courses. Thus, his estimate of the average course size is the average of the numbers reported by the students.(a) Does such a procedure serve his purpose?(b) If you answered yes to the previous question, explain why. If you answered no to the previous question, present a more efficient way.
