Suppose that A new president of a university has called for a survey of students in MNGT 368, to ask abut some positive metrics. Assume that 50% of all students would give affirmative responses, 30% would be neutral/ undecided, and the remaining 20% would give negative responses. Further assume that only affirmative responses are considered a success.
