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 14 randomly selected non-residential college students. Round answers to 3 decímal places where possible. 24 7 5 15 23 7 13 15 27 16 12 16 19 21 a. To compute the confidence interval use a ? distribution. b. With 95% confidence the population mean commute for non-residential college students is between and miles. c. If many groups of 14 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About these confidence intervals will contain the true population mean number of commute miles and about percent of percent will not contain the true population mean number of commute miles.
