An article in Technometrics (1999, Vol. 41. pp. 202-211) studied the capability of a gauge by measuring the weight of paper. The data for repeated measurements of one sheet of paper are in the following table. Construct a 99% one-sided, upper confidence interval for the standard deviation of these measurements. Assume population is approximately normally distributed.
