Question

A certain drug is known to be effective in treating a specific disease with a success rate of 60%. The use of the drug is considered successful when it heals the patient to a certain level. We want to determine the probability that the fifth patient who recovers is the seventh person to receive the medication during a specific week.

The sensitivity of a medical test is the true positive rate. In other words, the sensitivity is the probability that a person with the condition is correctly identified as having it. The specificity of a test is the true negative rate. In other words, the specificity is the probability that a person without the condition is correctly identified as not having it. We'll consider these ideas in the context of rapid strep tests. Rapid strep tests are useful because the standard way to test for strep throat is to take a throat culture, which can take a few days to come back. If the rapid test comes back positive, the patient can get started on treatment right away and get better more quickly. If the test comes back negative but the physician is still concerned the patient might have strep, they will sometimes call for the throat culture at that point. On average, rapid strep tests have been found to have 86% sensitivity and 95% specificity. Let's suppose we are dealing with a rapid strep…
A blood test indicates the presence of a particular disease 94% of the time when the disease is actually present. The same test indicates the presence of the disease 0.7% of the time when the disease is not present. 3% of the population actually has the disease. Calculate the probability that a person has the disease, given that the test indicates the presence of the disease.

A certain disease has an incidence rate of 0.8%. If the false negative rate is 8% and the false positive rate is 3%, compute the probability that a person who tests positive actually has the disease.
A drug test correctly gives a positive result 90 percent of the time. However, 3 percent of the time, it incorrectly gives a positive result. This is known as a false positive. Suppose that 7 percent of the people to be tested will have one or more of the drugs being tested for in their system. What is the probability that a randomly chosen person will have get a positive test result? Your answer should be to 4 decimal places.
