Task 2. Errors. Specificity and sensitivity To examine the specificity of a new PCR-type test, it has been used on 1000 healthcare workers in a high-risk environment who had symptoms, knowing that 50 % of them had COVID. The results obtained are summarized in this table: With COVID WITHOUT COVID Total Positive 457 7 464 Negative 43 493 536 Total 500 500 Calculate the significance a, tolerance ẞ, specificity 1-a and sensitivity 1-ẞ of this PCR test. What type of error is most likely in this test? Interpret the results.
