You are interested in finding a 90% 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. 10 22 22 23 10 7 13 26 16 15 24 5 15 a. To compute the confidence interval use a distribution. OF b. With 90% 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 90 ✓percent of these confidence intervals will contain the true population mean number of commute miles and about 10 ✓percent will not contain the true population mean number of commute miles.
