Suppose that a chewing gum company claims that 87% of dentists recommend their chewing gum. Dustin wants to test if this is true. He surveys 57 dentists. 1. Assuming the chewing gum company's claim is true, what is the probability that fewer than 77% of the dentists surveyed recommend the chewing gum? 2. If Dustin does find that fewer than 77% of the dentists surveyed recommend the chewing gum, would you doubt the chewing gum company's claim? Why or why not? (Consider this question on your own. You do not have to provide an answer here.)

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

4. If a randomly chosen athlete tests negative, what’s the probability that the student took a banned substance? Explain why it makes sense for the drug-testing process to be designed so that this probability is less than the one you found in Question 3.5. The district decides to immediately retest any athlete who tests positive. Assume that the results of an athlete’s two tests are independent. Find the probability that a student who gets a positive result on both tests actually took a banned substance. Based on your answer, do you think that an athlete who tests positive twice should be suspended from athletic competition for a year? Why or why not?
