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, UCLR = 1.141, LCLR = 0. Over the past few days, they have taken five random samples four loaves each and have found the following.

Is the process still in control? Explain why or whynot.
