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?

A health educator wants to evaluate the effect of a dental film on the frequency with which children brush their teeth. Eight randomly chosen kids are measured on the number of times they brushed their teeth for one month before viewing the dental film and again for a month after the film. Child Before After 1 23 27 2 28 29 3 22 25 4 30 30 5 26 25 6 24 28 7 25 28 8 22 24 Therefore, the research hypothesis is that the dental film is effective at changing the frequency with which children brush their teeth. Hint: Make sure you do After-Before. Step 1. Express the substantive question as two statistical hypotheses. H0: Answer Answer Answer H1: Answer Answer Answer Step 2. Draw the sampling distribution under the null hypothesis using the p < .05 as the criterion for statistical significance to determine the critical values. What is the center of the distribution?
