To print 8.5×5.5.note pads, a copy shop uses standard 8.5× 11 paper,glues the long edge, then cuts the path in half so that the pad with is 5.5 inches. However,there is variation in the cutting process set up a control chart for the mean width of a note pad, assuming that, in the future,pads will be sampled in random subgroups of 5 pads.Use this sample of 40 observations (widths in.inches) to estimate and
