Font Paragraph Styles Q. 1 The results of the evaluation of a screening test for breast cancer among 64,810 subjects show that: There were 177 women who were ultimately found to have had breast cancer, and 64,633 women remained free of breast cancer during the study. Among the 177 women with breast cancer, 132 had a positive screening test (true positives), but 45 had negative tests (false negatives). Among the 64,633 women without breast cancer, 63,650 appropriately had negative screening tests (true negatives), but 983 incorrectly had positive screening tests (false positives). Define sensitivity, specificity, predictive value positive and predictive value negative for the scenario. Define the likelihood ratio (plus and negative) for this scenario. Find also Confidence intervals. Find (i) Youden's Index and (ii) Index of validity and efficiency. Comments on your results. 237 words DA English (United States) 2 Accessibility Good to go
