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 12 randomly selected non-residential college students.
14 | 12 | 8 | 9 | 28 | 9 | 9 | 27 | 14 | 20 | 15 | 17 |
a. To compute the confidence interval use a ? distribution.
b. With 95% confidence the population
c. If many groups of 12 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.
