Chapter 4, Problem 7T
Exam Review A professor is preparing an extra review session the Monday before final exams and she wants as many students as possible to be able to attend. She asks all of the students to rank different times of day in order of preference. The results are given below.
a. Using the plurality with elimination method, for what time of day should the professor schedule the review session?
b. Use the Borda count method to determine the best time of day for the review.
