Of the 100 HIV-infected patients, 95 had a positive test, while 5 had a negative test. A second group of 100 known HIV negative patients also underwent testing with the new diagnostic test. Of the 100 HIV negative patients, 92 had a negative test, while 8 had a positive test. What is the likelihood ratio of a negative test?
