The results of a study conducted on ???? = 1500 women at the Gynecological Oncology unit at Indira Gandhi Institute of Medical Sciences, Patna, India were reported in the article “Evaluation of sensitivity and specificity of pap smear, LBC and HPV in screening of cervical cancer” in the Indian Journal of Gynecologic Oncology

(Pankaj, 2018). The authors report an estimated prevalence of patients having epithelial cell abnormalities on Pap smear of 5%, an estimated sensitivity of the Pap smear test of 75.80%, and an estimated specificity of the Pap smear test of 98.05%. Using the authors information, compute an estimate of the

(a) positive predictive value for this test.

(b) negative predictive value for this test.
