A​ new, simple test has been developed to detect a particular type of cancer. The test must be evaluated before it is put into use. A medical researcher selects a random sample of 2000 adults and finds​ (by other​ means) that 2​% have this type of cancer. Each of the 2000 adults is given the​ test, and it is found that the test indicates cancer in 99​% of those who have it and in 2​% of those who do not. Based on these​ results, what is the probability of a randomly chosen person having cancer given that the test indicates​ cancer?

A​ new, simple test has been developed to detect a particular type of cancer. The test must be evaluated before it is put into use. A medical researcher selects a random sample of 2,000 adults and finds​ (by other​means) that 3​% have this type of cancer. Each of the 2,000 adults is given the​ test, and it is found that the test indicates cancer in 97​% of those who have it and in 1​% of those who do not. Based...

Suppose a test for cancer is given. If a person has cancer, the test will detect it in 96% of the cases; if the person does not have cancer, the test will show a positive result 1% of the time. If we assume that 12% of the population taking the test actually has cancer, what is the probability (rounded to the nearest percent) that a person taking the test and obtaining a positive actually has cancer?

"To diagnose colorectal cancer, the hemoccult test is conducted to detect occult blood in the stool. For symptom-free people over 50 years old who participate in screening using the hemoccult test, the following information is available. The probability that one of these people has colorectal cancer is 0.3 percent. If a person has colorectal cancer, the probability is 50 percent that he will have a positive hemoccult test. If a person does not have colorectal cancer, the probability is 3...

A new, non-invasive colon cancer screening method boasts a sensitivity of 99%. That is, given that a patient has colon cancer, the screening method has a 0.99 probability of yielding a positive test. The test is also 90% specific, meaning that if a person without colon cancer is screened, there is a 0.9 probability of a negative test result. Among the population of adults over 45 years of age, the proportion who have colon cancer is 0.0013 (thirteen out of...

A test for detecting cancer which appears to be promising has been developed. It was found that 98% of cancer patients in a hospital reacted positively to the test while 4% of those without cancer reacted positively. 3% of the patients in the hospital have cancer. Let P(C) = Probability of a patient having cancer Let P(NC) = Probability of a patient not having cancer Let P(P+) = Probability of a patient getting a positive result Let P(P-) = Probability...

The sensitivity of a medical test refers to the test’s ability to correctly detect ill patients who have the condition. Mathematically, sensitivity is equivalent to the probability that the test indicates a patient is ill given that the patient is ill. The specificity of a medical test refers to the test’s ability to correctly detect that a healthy patient does not have the condition. Mathematically, specificity is equivalent to the probability that the test indicates the patient is healthy given...

A new drug has been developed to treat a particular condition, and it is alleged to be more effective than traditional treatment. An experiment will be conducted to test whether the claim is true. To perform the hypothesis test, a 99% confidence level is selected for the hypothesis test. The new drug will be administered to a sample of 200 individuals with the condition, selected at random. Another 300 individuals are randomly selected to receive the traditional treatment. Of the...
