A hospital is trying to understand the effectiveness of a test in diagnosing a disease. The following are facts about the disease and the test.

P(having disease) = .08

P(NOT having disease) = .92

P(negative test | NOT having disease ) = .87

P(positive test | having disease ) = .90

a) What is Pr(NOT having disease AND positive test)?

b) What is Pr(having disease | positive test)?

c) What is Pr(NOT having disease | negative test)?

A hospital is testing patients for a certain disease. If a patient has the disease, the test is designed to return a "positive" result. If a patient does not have the disease, the test should return a "negative" result. No test is perfect though. 90% of patients who have the disease will test positive. 10% of patients who don’t have the disease will also test positive. 20% of the population in question has the disease. If a random patient tests...

A new diagnostic test is created to assist in detection of a rare disease. During development, a study is conducted to evaluate the effectiveness of this new test. The test is run on 100 known cases and 200 controls. Results indicate that 90 of the cases yield positive tests, as do 30 of the controls. 07. The Positive Predictive Value for this test indicates that: A. The likelihood that a positive test result is predictive of disease is 30/120, or...

For disease X, there’s a new rapid and accurate test in the market. The sensitivity of the test is 90% (probability to correctly detect disease X with positive test result), and the specificity of the test is 99% (probability to correctly give negative result for disease X free case). The prevalence of the disease is 0.01% in the population. Write in as percentage without percentage sign and with three decimal places. What is Pr[ X | positive ]? (i.e. probability...

A screening test for a newly discovered disease is being evaluated. In order to determine the effectiveness of the new test, it was administered to 900 workers. 150 of the individuals diagnosed with the disease tested positive. A negative test finding occurred in 60 people who had the disease. A total of 50 persons not diseased tested positive for it. Assume the prior probability is not known. What was the sensitivity of the test? What was the specificity of the...

A certain deadly disease occurs in 1 percent of the population. A blood test for this disease has a 2 percent false positive rate, and a 5 percent false negative rate (i.e., 2 percent of those not having the disease test positive, and 5 percent of those having the disease test negative). Suppose you want to put your mind at ease and take the blood test. a) If you have the disease, what is the probability you would correctly get...

Suppose that a certain disease is present in 10% of the population, and that there is a screening test designed to detect this disease if present. The test does not always work perfectly. Sometimes the test is negative when the disease is present, and sometimes it is positive when the disease is absent. The following table shows the proportion of times that the test produces various results. Test Is Positive (P) Test Is Negative (N) Disease Present (D) 0.06 0.04...

When insurance companies establish policies for covering screening tests for diseases, one important factor is the value of the test predicting the disease. For example, for a certain type of disease, insurance companies may only cover the test costs if the test improves the prediction of having the disease by 90%. To help decide coverage policy for a new test, use the following data to help decide whether the test should be covered: Test Positive Test Negative Have Disease 11...

I'm not sure how to do this, I got it wrong. For disease Y, there’s a new rapid and accurate test in the market.

The prevalence of the disease is 1% in the population. Write in as percentage without percentage sign and with three...

The table below has probabilities for a given test to see if people have a certain disease. Based upon this table answer the questions that follow: Disease Clear (no disease) Positive test result (+) .12 .08 .20 Negative test result (-) .18 .62 .80 .30 .70        What is the positive predictive value?       What is the negative predictive value?        What is the false positive rate?       What would you say about the quality of this test based on these results?
