The following are summary statistics for a data set. Would it be appropriate to use the Student’s t distribution to construct a confidence interval from these data? Explain.
No. The maximum value is 39.920, yet the third quartile is only 8.103, and the interquartile range is 6.136. The distance between the third quartile and the maximum is thus more than 5 times the interquartile range. The maximum value is an outlier, so it is not appropriate to assume that this is a sample from a normal population.
