1. The number of women in this age group have a positive mammogram is 6432.
2. Out of 6432 with positive mammogram 302 actually have cancer.
3. The probability that a women in this age group has cancer if her mammogram was positive is = 302/6432= 0.046952
4. Yes it is unusual.

A newspaper on January 24, 1997, discussed the recommendation of a special panel concerning mammograms for women in their 40s. About 2 % of women aged 40 to 49 years old develop breast cancer in their 40s. But the mammogram used for women in that age group has a high rate of false positives and false negatives; the false positive rate is 0.22 , and the false negative rate is 0.24. If a woman in her 40s has a positive...
Breast cancer is the most common non-skin malignancy among women in the United States, and it is the second leading cause of death from cancer among women (lung cancer ranks Örst). A mammogram is a diagnostic procedure designed to quickly detect breast cancer. Such a test can exhibit two kinds of errors: One error is known as a false positive: The test incorrectly indicates cancer in a healthy woman. The other error (which is more serious error in this situation)...
Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 98 percent reliable, this means that the test will yield an accurate positive result in 98% of the cases where the disease is actually present. Gestational diabetes affects 9 percent of the population in our patient’s age group, and that our test...
