Sleeping outlier: A simple random sample of nine college freshmen were asked how many hours of sleep they typically got per night. The results were 8.5 9 24 8 6.5 6 9.5 7.5 7.5   Send data to Excel Notice that one joker said that he sleeps  24  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 an  80%  confidence interval for the mean amount of sleep from the remaining values. Round the answers to at least two decimal places.   An  80%  confidence interval for the mean amount of sleep from the remaining values is    <<μ   .
