Use the following information to solve the matching questions below. A 2X2 table is below the word problem to help guide you as to which values from the data provided go into the cells. A new test for the detection of baldness is devised. It is applied to a population of 200 men who live in the USA and insist that they have hair. Based on a gold standard--namely, asking the subjects to remove their hats--20 of the 200 men are actually bald. The new test detects 12 cases of baldness of which 8 are positive by the gold standard and 4 are negative. (Assume that none have shaved their heads.) Use the table below to determine which values go in cells a, b, c and d, then solve the problems below. Gold Standard (actually bald) Bald Not Bald Total New Test Positive A B 12 New Test Negative С 188 Total 20 180 200 Based on these data, the sensitivity of the new test is I Choose > The specificity of the new test is [Choose The positive predictive value of the new test in this population is [ Choose The negative predictive value of the new test is approximately [Choose
