You are interested in finding a 98% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 13 randomly selected non-residential college students. Round answers to 3 decimal places where possible. 13 6 14 20 21 15 15 9 26 8 25 5 10 a. To compute the confidence interval use a ? t z distribution. b. With 98% confidence the population mean commute for non-residential college students is between___ and___miles. c. If many groups of 13 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.
