Patsy Pennypincher is very concerned with the rising cost of education. She collected a sample of 20 institutions (n=20) and found a sample mean cost of $15,500 (x(with line above)=15,500) and a sample standard deviation to be $3000 (s = 3000). Provide Patsy with a 98% confidence interval for this year’s tuition cost.

A doctor's office
collected sample data for 25 patients, and found that they had to
wait an average of 35 minutes with a sample standard deviation of
10 minutes, in order to see the doctor. (The wait times were also
found to be normally distributed.) We are interested in calculating
a 98% confidence interval for the average waiting time for the
population of all patients.

The U.S. Department of Health, Education, and Welfare collected
sample data for 1555 women aged 18 to 24 years. This
sample group has a mean μ serum cholesterol level
(measured in mg/100 ml) of 193.7. Use this sample data to find the
97% confidence interval for the mean serum
cholesterol level of all women in the 18- 24 year age bracket.
Assume that the population standard deviation σ is
42.0.
