A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are centimeters on a pain scale before and after hypnosis. Assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval for the mean of the "before−after" differences. Does hypnotism appear to be effective in reducing pain?

You are interested in finding a 98% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 11 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 27 5 28 22 15 9 16 10 25 18 5 a. To compute the confidence interval use a Z OR T distribution. b. With 98% confidence the population mean number of visits per physical therapy patient is between ? and ? visits. c. If many groups of 11 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean number of visits per patient and about ? percent will not contain the true population mean number of visits per patient.
You are interested in finding a 99% confidence interval for the average commute that non-residential students have to their college.
