Organic 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: UCL = 5.58, LCL = 5.00; UCLR = 1.307, LCLR = 0. Over the past few days, they have taken five random samples of four loaves each and have found the following: Net Weight Sample Loaf # 1 Loaf # 2 Loaf # 3 Loaf # 4 5.7 5.8 5.7 5.9 5.2 5.2 5.3 5.2 4.5 4.7 4.9 4.8 UI A W N 5.2 5.2 5.4 5.5 4.8 4.7 4.8 4.9 Based on the x-chart, is one or more samples beyond the control limits
