A firm has new test to detect Covid. It researches the values of the test on thousands of people and find that if a person has Covid, then the test will detect it in 95% of the cases (correct positive); and if a person does not have Covid, it will still show a positive result in 4% of the cases (false positive). Later medical records show that 10% of the group actually did have Covid.
