Sleeping outlier: A simple random sample of ten college freshmen were asked how many hours of sleep they typically got per night. The results were24 86.5698.5 7.5 6.5 8.5 9.5Send data to ExcelNotice that one joker said that he sleeps 24 a day.Part: 0/3Part 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 fromthe 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 5.99<μ< 9.1259
