A new president at Big State University has made student satisfaction with the enrollment and registration process one of her biggest priorities. Students must see an advisor, sign up for classes, obtain a parking permit, pay tuition and fees, and buy textbooks and other supplies. During one registration period, 10 students every hour are sampled and asked about satisfaction with each of these areas. Twelve different groups of students were sampled, and the number in each group who had at least one complaint are as follows: 0,2,1,0,0,1,3,0,1,2,2,0.
Develop upper and lower control limits (99.7%) for the proportion of students with complaints.
