QUESTION 8 The sensitivity of a diagnostic test is the probability that the test will give a positive result when an individual has the disease being tested for. Suppose that a COVID-19 test is given to 100 people, 26 of which have the disease and 74 of which do not. Of those who have the disease, 23 test positive and 3 test negative; of the 74 who do not have the disease, 6 test positive and 68 test negative. Round your answer to three decimal places. What is the sensitivity of this test?
