Assume that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more? Why or why not? Given a business situation word problem or case study such as defective items or waiting lines, use discrete probability concepts to determine a course of action.
This week, we will be discussing Normal Probability Distributions and what is considered an unusual outcome. According to Lee (2018), he states that in probability, for an event to be considered unusual, the event should have the probability of less than 5%.
