Suppose a new infectious disease has just entered into public transmission. An epidemiologist has secured the medical records of 622 cases and 1309 controls. The epidemiologist wishes to estimate the odds ratio for a hypothesized exposure variable. When looking back into the records the epidemiologist discovers that of the cases 498 were exposed to the risk factor and of the controls 872 were exposed. Estimate the odds ratio to the nearest thousandth:

- Cases: Individuals who have the disease. - Controls: Individuals who do not have the disease. - Exposed: Individuals who were exposed to the risk factor. - Not Exposed: Individuals who were not exposed to the risk factor. Show more…

Suppose that one person in 100,000 has a particular rare disease for which there is a fairly accurate diagnostic test. This test is correct 99.0% of the time when given to a person selected at random who has the disease; it is correct 99.5% of the time when given to a person selected at random who does not have the disease. Given this information can we find (a) the probability that a person who tests positive for the disease has the disease? (b) the probability that a person who tests negative for the disease does not have the disease? Should a person who tests positive be very concerned that he or she has the disease?

A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.9. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.04. It is estimated that 15% of the population who take this test have the disease. If the test administered to an individual is positive, what is the probability that the person actually has the disease? Answer:

Suppose that the probability of suffering a side effect from a certain flu vaccine is 0.005. If 1000 persons are inoculated, find the approximate probability that At most 1 person suffers. 4, 5, or 6 persons suffer
