Question

It is estimated that approximately 10.5% of Americans are afflicted with diabetes. Suppose that a new diagnostic test is being checked for its accuracy. When the test is given to adults over 40 who have diabetes, it marks 95% positive for the disease (this is a correct diagnosis). When the test is given to adults over 40 who do not have diabetes, it marks 3.5% positive for the disease (this is an incorrect diagnosis). Round your final answers to three decimal places. (a) Find the probability that a randomly selected adult over 40 does not have diabetes, and is diagnosed as positive for diabetes by the new diagnostic test.
