Suppose that 20% of the cyclists racing in the Tour de France are using illegal performance enhancing drugs. They are tested one week prior to the start of the race. The blood test administered has a 5% false positive rate (that is, the probability of a positive result given the individual is not using an illegal performance enhancing drug is .05). The probability of a positive result given the individual is using an illegal performance enhancing drug is .90. Suppose that a randomly selected Tour de France participant tests positive for using an illegal performance enhancing drug. What is the probability that the individual is not guilty (that is, is not taking an illegal performance enhancing drug)?

(20 pt., 5 pt. each) A sports association decides to implement a drug screening procedure to test its athletes for illegal performance enhancing drugs. A person who does not take the drugs will test positive with probability 0.02 and a person who does take the drugs will test negative with probability 0.04. Suppose that 3% of the athletes tested take performance enhancing drugs What is the probability that an athlete testing positive takes the drugs? What is the probability that...

A supreme court from a certain region recently ruled that employees can be tested for drugs only if management has reasonable cause to administer the test. An article in a certain magazine focused on the misclassification rates of such drug tests. A false positive occurs when a drug test administered to a non-drug user yields a positive result. A false negative cours when a drug test administered to a drug user yields a negative result Complete parts a and b....

The college suspects their star player James Strongarm has used an illegal performance-enhancing drug. Currently, the probability that James is a drug user is 0.37. They consider barring him from athletics. The real "monetary" values of the outcomes are difficult to assess in this case and, therefore, the value of each outcome is expressed in a funny money unit: Galleon (from Harry Potter Movies). The following are the payoffs for the potential outcomes: Correctly identifying a drug user and barring...

Extra Credit: ELISA tests are used to screen donated blood for the presence of the AIDS virus. The test actually detects antibodies, substances that the body produces when the virus is present. When antibodies are present, ELISA is positive with probability about 0.997 and negative with probability about 0.003. When...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
