Question

A 1998 study examined the ability of a new screening test to detect Disease X in 880 individuals. Of those with Disease X, 76 screened positive with the new test. Of those without Disease X, 747 screened negative for Disease X. It was later confirmed that 88 of the 880 individuals actually had Disease X. Construct a 2x2 table and compute the positive predictive value of the new screening test.
