A firm hаs new test tо detect Cоvid. It reseаrches the vаlues оf the test on thousands of people and find that if a person has Covid, then the test will detect it in 97% of the cases (correct positive); and if a person does not have Covid, it will still show a positive result in 2% of the cases (false positive).
