Pulp brightness data

A manufacturer wants to evaluate the variability of their paper bleaching process. The manufacturer randomly collects 200 samples of pulp and records the brightness level. The manufacturer wants to calculate a range within which the brightness of at least 99% of the batches of pulp are expected to fall.

You can use this data to demonstrate Tolerance Intervals (Nonnormal Distribution).
