Problem
A new test for the detection of baldness is devised. It is applied to a population of 200 men. Based on a gold standard (having subjects 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. CONSTRUCT THE 2X2 TABLE.
What is the specificity of the new test?
