Specificity represents Group of answer choices the ability to distinguish between who has a disease and who does not. the proportion of nondiseased people who are correctly identified as “negative” by the test. the proportion of diseased people who were correctly identified as “positive” by the test. how well a treatment works under “ideal” conditions.

It is possible for medical tests to give incorrect results. Assume we are test- ing an individual for a disease. The sensitivity of a test is the probability that the test returns “positive” given the individual has the disease, while the specificity of a test is the probability that the test returns “negative” given the individual does not have the disease. Suppose it is known that (on average) 2 in every 1,000 adults has a particular disease at any given time. A test for the disease has a sensitivity of 0.98 and a false positive rate (that is, the probability of the test saying “positive” when the patient is actually negative) of 0.01. Determine: a) The probability an individual has the disease given the test is positive. b) The probability an individual has the disease given the test is negative. (This is called a false negative.)
