Question: Six cycles have been observed in a direct time study. The mean for the largest element is 0.82 min, and the corresponding sample standard deviation

Six cycles have been observed in a direct time study. The mean for the largest element is 0.82 min, and the corresponding sample standard deviation s is 0.11 min, which was also the largest. If the analyst wants to be 95% confident that the mean of the sample was within 0.10 min of the true mean, how many more observations should be taken?
