Probability that a test gives a positive result when someone has an illness is 0.98, and gives a positive result when the person does not have the illness is 0.02. The incidence of illness in the population is 0.01.

Suppose a person takes the test and the result is positive. What is the probability that the person has the disease?

1) With probability 0.82, a test will give a positive result when applied to a person with a certain disease and will give a positive result when applied to someone without the disease with probability 0.8. Given that 7% of the population have the disease, what is the probability that a person that tests positive for the disease actually has the disease?

1.      A diagnostic test has a probability 0.95 of giving a positive result when applied to a person suffering from a certain disease, and a probability 0.10 of giving a (false) positive when applied to a non-sufferer. It is estimated that 0.5 % of the population are sufferers. Suppose that the test is now administered to a person about whom we have no relevant information relating to the disease (apart from the fact that he/she comes from this population). Calculate...

Q1. If the individual have the disease the probability is .95 that the test gives positive diagnosis where if the individual does not have the disease the probability is 0.98 that the test gives negative diagnosis. Assume that 8% of tested people have the disease. Answer the following: What is the sensitivity and the specificity of the test? If an individual has diagnosed positive what is the probability that he actually has the disease? Q2. for the BP measurements of...

The probability that a person actually has the disease is 0.3, implying that out of 1000 people, 30 people have the disease. A new test has a false positive probability of 0.01 and a false negative probability of 0.02. A person is given the test and the result is positive, what is the probability they actually have the disease?

A new medical procedure has been shown to be effective in the early detection of a novel virus. A medical screening of the population is proposed. Let D denote the event that one has the disease, then D’ denotes the event that one doesn’t have the disease. Let + denote the event that the test signals positive, and – denote the event that the test signals negative. The probability that a new medical procedure correctly identifies someone with disease as...

The test for a disease has a false positive rate of 5% and a false negative rate of 3%.  Suppose a person to be test has the disease with probability 20%. If the test is positive, what is the revised probability that the person has the disease? If the test is negative, what is the revised probability that the person has the disease? If the test is negative, what is the revised probability that the person does not have the disease?...

Suppose that a rare disease occurs in the general population in only one of every 10,000 people. A medical test is used to detect the disease. If a person has the disease, the probability that the test result is positive is 0.99. If a person does not have the disease, the probability that the test result is positive is 0.02. Given that a person’s test result is positive, find the probability that this person truly has the rare disease?

A test for a particular illness that affects 3% of the general population has the following properties: The test will show a positive in 97% of cases where the patient has the illness and a negative in 3% of such cases. The test will show a false positive in 6% of patients who do not have the illness and a negative result for 94% of patients who do not have the illness. Note that a positive result means that the...
