leeping outlier: A simple random sample of nine college freshmen were asked how many hours of sleep they typically got per night. The results were 24  8.5 9 8 6.5 7.5 6 8.5 9.5     Notice that one joker said that he sleeps 24HRS   a day. Part: 0 / 3 0 of 3 Parts Complete   Part 1 of 3     (a) The data contain an outlier that is clearly a mistake. Eliminate the outlier, then construct a   confidence interval for the mean amount of sleep from the remaining values. Round the answers to at least two decimal places.   A 99.5%   confidence interval for the mean amount of sleep from the remaining values is       .
