A diagnostic test is being developed to identify two groups of patients, those b. Determine how well the test identifies the two groups by calculating the sensitivity are given in the histogram below. Assuming a test threshold of 58 (i.e, a test resut above (probability that an exposed patient tests positive) and specificity (probability that who haven't been exposed to a pathogen (with low test values) and those who have beem exposed (with high test values). Actual measured values for patiets with knowm exposures 58 is a positive test for exposure): a. Fill in the confusion matrix an unexposed patient tests negative) for the test. Patient Test Values 30 25 25 20 19 19 17 16 15 15 14 12 11 11 10 40.0 42.5 45.0 47.5 50.0 52.5 55.0 57.5 60.0 62.5 65.0 67.5 70.0 725 75.0 775 BOD Test Value Unexposed patients Exposed patients High Test Value (+) Low Test Value (-) Total Exposed Patients Unexposed Patients Total
