The following are the number of pounds per day shipped by a trucking company.

It is suggested that the shipments be treated as a process. Because these data are not symmetrically distributed, you could try a transformation. For the choice of the fourth root of weight, set the specification limits LSL and USL symmetrically about 22.6 (pounds \(^{1 / 4}\), so that the estimated capability index \(\widehat{C}_{p k}\) is 1.5 .
