My information says 95% not 99%

Sleeping outlier ; A simple random sample of eight college freshmen were asked how many boors of sleep they typically got per night , The results were 7.5 8. 0 6 . 5 2 . 4 8 . 5 6.5 7.0 7.5. Notice that one joker said that he sleeps 24 hours a day, 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 remain ing values , b- Leave the outlier in and construct the 950 confidence interval , Are the results noticeably diffrent ? Explain why it is important to check data for outliers .Sleeping outlier : A Simple random sample of eight college freshmen were asked hour many boors of sleep they typically got per night , The results were 7.5 8. 0 6. 5 2.4 8. 5 6.5 7.0 7.5.
