A test with 99% sensitivity and 95% specificity is applied to three populations. Population A has a prevalence of 3%. Population B has a prevalence of 11%. Population C has a prevalence of 25%. Each population has exactly 1000 people. NOTE: you cannot not have portions of people so you need to round your numbers up or down. Please complete the following table:
Population | A | B | C |
Number in Population | 1000 | 1000 | 1000 |
Prevalence | 3% | 11% | 25% |
