Probabilities are useful in the decision-making process. Suppose a random sample of 152 students was surveyed regarding an instructor's teaching. Suppose 105 students rated the instructor either excellent or above average on lecture presentations, 96 students rated the instructor as giving difficult or very difficult assignments and tests. Would you take this instructor for a class? Discuss the influence of probabilities on making this decision.
