Whole Grains LLC uses statistical process control to ensure that its health-conscious, low fat, multigrain sandwich loaves have the proper weight. Based on a previously stable and in-control process, the control limits of the x and R-charts are:
UCLx=6.56. LCLx = 5.84, UCL r= 1.141, LCLr = 0. Over the past few days, they have taken five random samples of four loaves each and have found the following:
