Question 1101835
Consider a sample size of 100000. Then, out of these 100,000, .6%, or .006 actually have the disease. That is, 600 actually have the disease. Out of these 600, 36 will test negative, 564 will test positive. Of the 99400 who don't have the disease, 994 will test positive, 98406 will test negative. The true ratio of people who have the disease, versus those with positive results, would be
564/564+994=0.362, or  36.2%
