The number of cups of coffee enjoyed in a month by randomly selected 50-year-old women and men is listed here.

women	29	25	17	36	41	25	32	29	38	34	24	27	29
men	41	41	37	29	30	38	39	10	29	55	29

Construct a 90% confidence interval and conduct a hypothesis test at a = 0.10 significance level to determine if there is sufficient statistical evidence to conclude that there is a difference in the number of cups of coffee enjoyed in a month by women and by men.

A certain group of symptom-free women between the ages of 40 and 50 are randomly selected to participate in mammography screening. The incidence rate of breast cancer among such women is 0.8%. The false negative rate for the mammogram is 10%. The false positive rate is 7%. If a the mammogram results for a particular woman are positive (indicating that she has breast cancer), what is the probability that she actually has breast cancer?

A record of Starbucks coffee shop at Ball State shows that the mean number of cups of coffee consumed by a science-major student is 6 per week. A student in STATs class feels it is greater. She found that the average number of coffee cups had was 9 with a standard deviation of 2 cups for randomly selected 10 science-major students in a week. Assuming that the weekly consumption of coffee by science-major students is normally distributed, test her claim...
