Epidemiologists claim that the probability of breast cancer among Caucasian women in their mid-60s is 0.003. An established test identified people who had breast cancer and those that were healthy. A new mammography test in clinical trials has a probability of 0.90 for detecting cancer correctly. In women without breast cancer, it has a chance of 0.975 for a negative result. If a 65-year-old Caucasian woman tests positive for breast cancer, what is the probability that she, in fact, has breast cancer?

16. An epidemiologic study of breast cancer among elderly women followed 1,000 women, 65-79 years of age, without evidence of breast cancer over several years. Every two years the investigators examined the women for breast cancer. The results were as follows: 12 new cases at the first evaluation, 11 new cases at the second evaluation, 23 new cases at the third evaluation, and 28 new cases at the fourth (and final) evaluation. The investigators also noted that 40 women had...

Epidemiologists decided to investigate the validity of new diagnostic tool for breast cancer. They used this new diagnostic tool for breast cancer in 150 women with biopsy-proven breast cancer in 300 age- and race-matched control women. The results of the new tool were positive in 136 cases and in 35 control women, all of whom showed no evidence of cancer at biopsy. What is the sensitivity of new diagnosis tool for breast cancer? a. 33% b. 91% c. 9% d....

Patients with breast cancer sometimes die for other reasons. In a Nurses’ Health study, women with breast cancer were followed for 10 years and 2.5% had incidence of heart disease. Suppose the baseline 10-year incidence rate of heart disease in the general population is 2%. Assume a study is to be undertaken tracking women with breast cancer to see if there is a difference in the heart disease rate from the general population. Assuming the true heart disease incidence rate...

A method currently used by doctors to screen women for possible breast cancer fails to detect cancer in 20% of the women who actually have the disease. A new method has been developed that researchers hope will be able to detect cancer more accurately. A random sample of 81 women known to have breast cancer were screened using the new method. Of these, the new method failed to detect cancer in 14. Let p be the true proportion of women...
