Approximately 3% of women aged 40-50 have breast cancer. A woman with breast cancer has a 90% chance of positive test from a mammogram, while a woman without breast cancer has a 2% chance of a positice result. What is the probability that a woman has breast cancer given that she just had a positive test?

B) Epidemiologists claim that the probability of
breast cancer among
Caucasian women in their mid-50s is 0.005. 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 0.85 for
detecting
cancer correctly. In women without breast cancer, it has a chance
of 0.925
for a negative result. If a 55-year-old Caucasian woman tests
positive for
breast cancer, what is the probability that she, in fact,...

The following table contains statistics from a logistic
regression analysis for a study on intravenous drug use among high
school students in United States. Drug use is characterized as a
dichotomous variable, where 1 indicates that an individual has
injected drugs within the past year and 0 that he or she has not.
Factors that might be related to drug use are instruction about the
HIV in school (1 represents "had HIV education" and 0 represents
