A medical test has been designed to detect the presence of a certain disease. Among people who have the disease, the probability that the disease will be detected by the test is 0.93. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.03. It is estimated that 3% of the population who take this test have the disease. (Round your answers to three decimal places.) (a)...

A certain virus infects 10 in every 1000 people.   A test used to detect the virus in a person is positive 80% of the time when the person has the virus (20% false negative), and 5% of the time when the person does not have the virus (5% false positive). That is 20% of of the time when the test should be positive but didn't, and 5% of the time the test indicated positive and shouldn't. 1) Out of all...
