Sleeping outlier: A simple random sample of ten college freshmen were asked how many hours of sleep they typically got per night. The results were 24 8 6.5 6 9 8.5 7.5 6.5 8.5 9.5 Send data to Excel Notice that one joker said that he sleeps 24 a day. Part 1 of 3 (a) The data contain an outlier that is clearly a mistake. Eliminate the outlier, then construct a 95% confidence interval for the mean amount of sleep from the remaining values. Round the answers to at least two decimal places. A 95% confidence interval for the mean amount of sleep from the remaining values is 6.83 << 8.72 Part: 1/3 Part 2 of 3 (b) Leave the outlier in and construct the 95% confidence interval. Round the answers to at least two decimal places. If the outlier is included the 95% confidence interval is << S 99
