A research study found that on average, people illegally use prescription drugs 5 times a year. We think that the population average is different than this. We talk to 12 people and find an average of 2.14 with a standard deviation of 2.04. Conduct a hypothesis test to see if the population average is different. Use an alpha level of 0.05. What’s your alternative hypothesis? a. H1: µ ≠ 2.14 b. H1: µ > 5 c. H1: µ > 2.14 d. H1: µ ≠ 5
