There is a brand new blood test for a certain virus that will determine whether you have been exposed to the virus. It is known that in the population, 7.3% have been exposed to the virus. If the patient has been exposed to the virus, then the test returns
• positive 63% of the time
• negative 23% of the time
• INCONCLUSIVE 14% of the time
If the patient hasn't been exposed to the virus, then the test returns
• negative 91.5% of the time
• positive 1.5% of the time
• INCONCLUSIVE 7.0% of the time
(a) What is the probability that you get an INCONCLUSIVE result?

(b) What is the probability of a true positive? A false negative?

    In a laboratory, blood test is 95% effective in detecting a certain disease, when it is, in fact, present. However, the test also yields a false positive (test is positive but patient does not have the disease) result for 1% of the healthy people tested. 0.5% of the population actually has the disease. Given this information, calculate the following probabilities: The probability that the test is positive. Given a negative result, the probability that the person does not have the...

    A certain virus infects one in every 300 people. A test used to detect the virus in a person is positive 80% of the time when the person has the virus and 15 % of the time when the person does not have the virus. (This 15 % result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive." (a) Using Bayes' Theorem, when a person tests...

    A certain virus infects one in every 200 people. A test used to detect the virus in a person is positive 80% of the time if the person has the virus and 5% of the time if the person does not have the virus. Using Bayes' Rule, if a person tests positive, determine the probability the person has the virus. Round to four decimal places.

    Problem Nine A test for a certain disease was given to 1,000 subjects, 8% of whom were known to have the disease. For the subjects who had the disease, the test had a positive result for the disease in 90% of the subjects, was inconclusive for 7% and a negative result in 3% of the subjects. For subjects who did not have the disease, the test had a positive result in 5% of subjects, was inconclusive in 10% and a...
