The table to the right is based on the assumption that \"it: of breast tumors are malignant. It also #14 assumes that mammogram screening is 90% accurate. Complete parts (a) through (c) below. Positive Mammogram Negative Mammogram a. Suppose a patient has a positive mammogram. What is the chance that she really has cancer? Est (Type an integer or decimal rounded to the nearest tenth as needed.) b. What is the chance of a positive mammogram. given that the patient has cancer? Est (Type an integer or decimal rounded to the nearest tenth as needed.) C. Suppose a patient has a negative mammogram. What iS the Chance that she actually does have cancer? Est (Type an integer or decimal rounded to the nearest hundredth as needed.) Suppose that a test for performance-enhancing drugs is 85% accurate (It will correctly detect 85% of people who use such drugs and will correctly detect 85% who do not). Suppose that, 10% of the 200 athletes in a major meet have actually #15 taken performance-enhancing drugs, and all athletes are given the drug test. Complete parts (a) through (c) below. Users Non-Users Total Test finds drug use 17 27 44 Test finds no drug use 3 153 156 Total 20 180 200 a. Verify that the entries in the table above agree with the information given. Explain each entry. The table shows a total of athletes tested. The total number of athletes using performance-enhancing drugs is , which is % of the total athletes tested. The test correctly detected |athletes using, which is % of the total athletes using. The test correctly detected | athletes not using, which is |% of the total athletes not using. Therefore, the table with the information given. (Type whole numbers.) b. How many athletes in total were accused of using performance-enhancing drugs? Of these, how many were using and how many were not? What percentage of those accused of using were falsely accused? There were athletes in total that were accused of using performance-enhancing drugs. (Type a whole number.) Of those accused, athletes were using. (Type a whole number.) Of those accused, athletes were not using. (Type a whole number.) The percentage of those accused of using who were falsely accused is% (Type an integer or decimal rounded to one decimal place as needed.) c. How many athletes in total are cleared of using performance-enhancing drugs? Of these, how many were actually using the drugs? What percentage does this represent of those cleared? There were athletes cleared of using performance-enhancing drugs. (Type a whole number.) Of those cleared, athletes were actually using the drugs? (Type a whole number.) The percentage of those cleared who were actually using the drugs is% (Type an integer or decimal rounded to one decimal place as needed.)Step by Step Solution
