A screening test for a specific disease is being evaluated. In order to evaluate the effectiveness of the new test, it is administered to 700 people in a given community. 120 of the individuals who had the disease tested positive and 80 tested negative on the screening test. A total of 50 people without disease tested positive. What is the predictive value positive of the screening test?

    A new screening test for colon cancer is developed. The screening test is evaluated by comparing results of 500 patient MRI results (in this case, considered the “gold standard” or confirming diagnostic tool). Of the 264 people who had a positive result on the new test, 211 were confirmed to have the disease by the MRI. Of the 236 people who had a negative result on the test, 97 were confirmed to have the disease by the MRI. Please calculate...

    2. Two simple and inexpensive screening methods have been developed to identify individuals with HIV infection at routine medical check-ups. To study the sensitivity and specificity, both methods were tested on 12860 persons who underwent a simultaneous and thorough clinical examination that was considered to give an accurate diagnosis. There were 1900 cases of disease as diagnosed by clinical methods. The Screening test #1 was positive for a total of 1000 people, including 800 with active HIV infection. The screening...
