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 two decimal places.A95

%

confidence interval for the mean amount of sleep from the remaining values is

Please provide a step by step example of the sample mean and sample standard deviation. Thank you
