Module 12 Task A new test was developed to rapidly test for COVID19. You are asked to assist with the validation. The rapid test was run on 1579 symptomatic people. Samples from patients were divided into those with confirmed COVID 19 and those not infected using a gold standard diagnostic. The following table shows the distribution of the new rapid test results on the 1579 people. Rapid test result No infection Infection High likelihood 718 0 Moderate-likelihood 372 10 Moderate - high likelihood 150 64 Low-moderate likelihood 4 82 Very low likelihood 0 178 1. Construct the 2 by 2 table for rapid test versus the gold standard when a cutoff of moderate-high likelihood or greater is used for classification (equal or greater is positive 2. Calculate and interpret the sensitivity of the Test. 3. Calculate and interpret the specificity of the test. 4. Calculate and interpret the predictive value positive of the test. 5. Calculate and interpret the predictive value negative of the test
