Only 5 out of 1000 people get sick from a specific disease. A test for the disease is 99% accurate. This test also has a 2% false positive result (2% of the people that test positive are actually not sick with the disease). What is the probability that if you receive a positive test result, that you actually have the disease?

Answer #1

Solution:- The probability that if you receive a positive test result, that you actually have the disease is 0.1992

P(Disease) = 5/1000 = 0.005

P(Not Disease) = 1- 0.005 = 0.995

    3. Assume 6% of people have a certain disease. A test gives correct diagnosis with probability 0.85 i.e. if the person is sick, the test will be positive with probability 0.85, but if the person is not sick, the test will be positive with probability 0.15. A random person from the population has tested positive for the disease. What is the probability that he is actually sick? Part 2. Random Variables

    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...

    2. Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 99 percent reliable, this means that the test will yield an accurate positive result in 9 of the cases where the disease is actually present. Gestational diabetes affects #.1 percent of the population in our patient's age group, and that our...
