Hello,

Could you please help me with the following?

A serologic test is being devised to detect a hypothetical chronic disease. Three hundred individuals were referred to a laboratory for testing. One hundred diagnosed cases were among the 300. A serologic test yielded 200 positives, of which one-fourth were true positives.

Calculate the sensitivity, specificity, and predictive value of this test. (After setting up the REQUIRED and appropriate 2 by 2 table, find missing data by subtraction.)

Thank you! (:
