A rum producer monitors the position of its label on the bottle by sampling five bottles from each batch. One quantity measured is the distance from the bottom of the bottle neck to the top of the label. The process mean should be ?-1.8 inches. Past experience indicates that the distance varies with ?-0.13 inch. (a) The mean distance for each batch sample is plotted on an x control chart. Calculate the center line and control limits for this chart....

A rum producer monitors the position of its label on the bottle by sampling four bottles from each batch. One quantity measured is the distance from the bottom of the bottle neck to the top of the label. The process mean should be μ = 1.6 inches. Past experience indicates that the distance varies with σ = 0.15 inch. (a) The mean distance x for each batch sample is plotted on an x control chart. Calculate the center line and...
