You are interested in finding a 95% confidence interval for the average commute that non- residential students have to their college. The data below show the number of commute miles for 11 randomly selected non-residential college students. Round answers to 3 decimal places where possible. 8 8 28 7 22 13 24 8 24 8 24 a. To compute the confidence interval use at distribution. b. With 95% confidence the population mean commute for non-residential college students is between and miles. c. If many groups of 11 randomly selected non-residential college students are surveyed, 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 commute miles and about percent will not contain the true population mean number of commute miles.

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 12 randomly selected physical therapy patients. Round answers to 3 decimal places where possible.   25 14 23 8 6 15 18 5 8 17 9 7   a. To compute the confidence interval use a ? z t Correct distribution. b. With 98% confidence the population mean number of visits per physical therapy patient is between blank and  blank visits. c. If many groups of 12 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.
