The probability that a person has a certain disease is 0.30. Medical diagnostic tests are available to determine whether the person has the disease. If the disease is actually​ present, the probability that the medical diagnostic test will give a positive result​ (indicating that the disease is​ present) is 0.92. If the disease is not actually​ present, the probability of a positive test result​ (indicating that the disease is​ present) is 0.01.If the medical diagnostic test has given a positive result​ (indicating that the disease is​ present), what is the probability that the disease is actually​ present? The probability is?

The probability that a person has a certain disease is 2%. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic tests will give a positive result (correct diagnosis) is 95%. If the disease is not actually present, the probability of a positive test result (incorrect diagnosis) is 0.5%. Suppose that the medical diagnostic test shows a positive result, (a) What is the probability...

A medical test is available to determine whether a patient has a certain disease. To determine the accuracy of the test, a total of 10,100 people are tested. Only 100 of these people have the disease, while the other 10,000 are disease free. Of the disease-free people, 9800 get a negative result, and 200 get a positive result. The 100 people with the disease all get positive results. Use this information as you answer the questions below. 1) Find the...

3. A diagnostic test has 95% sensitivity (the probability a person with the condition tests positive = 0.95) and 95% specificity (the probability a person without the condition tests negative = 0.95). In a population of people given the test, 1% of the people have the condition (probability a person has the condition = 0.01). (a) What proportion of the people will test positive? (b) Given a person has tested positive, what is the probability he/she has the condition?

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?

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?

Sensitivity and specificity essential characteristics of medical tests. Sensitivity is the probability that the test will indicate “disease” given that the individual actually has the disease, and specificity is the probability that the test will indicate “no disease” given that the individual does not have the disease. Answer the following questions for a test with sensitivity 75% and specificity 99%. Let p denote the prevalence of the disease (i.e., proportion of the population with the disease). (a) For p =...

A diagnostic test for a certain disease is believed to be 90% accurate in detecting the disease when in fact the person has the disease. Also, the test is believed to be 90% accurate in denying the disease when in fact the person does not have it. Only 1% of the population has the disease. A person is selected at random and the diagnostic test confirms the presence of the disease, what is the probability that the person actually has...
