Without doing the calculations, explain whether a 90% confidence interval for the population mean would be wider than, narrower than, or the same as that found in part (a). Choose the correctanswer belowOA. It will be narrower because the reliability factor will be smaller for a 90% confidence interval than for a 99% confidence intervalOB. It will be wider because the reliability factor will be smaller for a 90% confidence interval than for a 99% confidence interval.OC. It will be the same because the confidence interval is being calculated for the same data setOD. It will be wider because the reliability factor will be larger for a 90% confidence interval than for a 99% confidence interval

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. 11 10 17 10 27 15 20 8 10 8 12 a. To compute the confidence interval use a ?v 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.
