Medical screening tests are used to check for the presence on disease, evidence of illegal drug use, etc. The its sensitivity and its specificity. The sensitivity among those with the condition that will test positive. The specichy proportion among those without the condition that will test neg sensitivity of a test is defined to be the conditional ng those without the condition that will test negative. More formally, the test is defined to be the conditional probability that a person...

Which of the following conditions does not justify compromising specificity and increasing sensitivity of a screening test? (a) When the disease can spread rapidly through the population. (b) when the diesase is fatal if not treated early. (c) When the disease has no known treatment and morbitiy and mortality cannot be altered after early detection. (d) when diagnosing the disease early clearly has cost benefit and reduces morbidity.

Health experts’ estimate for the sensitivity of coronavirus tests, as they are actually used, is 0.7. They also think the specificity is very high. Suppose specificity is 0.99 and that the health experts’ estimated sensitivity is correct (0.7). a. In a population where 20% of the population is infected with the coronavirus, what is the probability that a person who tests positive actually is infected? b. Continued. What is the probability that a person who tests negative actually is not...
