Textbook Question
Chapter 1, Problem 27CE
The Graduate Management Admission Test (GMAT) is used by many graduate schools of business as one of their admission criteria. Using your own reasoning and concepts in this chapter, criticize each of the following conclusions.
- a. “Last year, 7,573 computer science majors took the GMAT, compared with only 588 philosophy majors. Philosophy majors must not be interested in business because so few take the GMAT.”
- b. “Last year, 29,688 engineering majors took the GMAT, compared with only 3,589 English majors. Clearly, more students major in engineering than in English.”
- c. “Last year, physics majors averaged 100 points higher on the GMAT than marketing majors. If marketing students majored in physics, they would score better on the GMAT.”
- d. “On average, physics majors score higher on the GMAT than accounting majors. Therefore, physics majors would make the best managers.”
