2.Prof. Roberto Claudio was the Director of Student Services in the business school of a major university. He wanted to conduct a survey of both the Bachelor in Business Administration and Master in Business Administration students to determine their attitudes toward course offerings, counseling services available and job opportunities. There were a total of 4,000 BBA students and 800 MBA students in the business school. Since a census was not possible, Prof. Claudio needed to develop a sampling design.
