A reseаrch teаm set оut tо determine the diаgnоstic accuracy of a physical examination to screen for breast cancer. Results of the physical exam were compared to a gold standard of the presence of biopsy-proven adenocarcinoma of the breast. The physical examination was used to screen for breast cancer in 3,000 women with biopsy-proven adenocarcinoma of the breast (the gold standard) and in 6,000 age- and race-matched control women (without biopsy-proven adenocarcinoma of the breast). The results of the physical examination were positive (i.e., a mass was palpated) in 1,800 women with biopsy-proven adenocarcinoma of the breast and in 800 control women who showed no evidence of cancer at biopsy. What was the specificity of the physical examination? Give your answer as a percentage. (Hint: construct a two by two table to help you complete this calculation.)
