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_x^- = 6.56. LCL_x^- = 5.84, UCL_R^- = 1.141, LCL_R^- = 0. Over the past few days, they have taken five random samples of four loaves each and have found the following:

SAMPLE	NET WEIGHT
SAMPLE	LOAF #1	LOAF #2	LOAF #3	LOAF #4
1	6.3	6.0	5.9	5.9
2	6.0	6.0	6.3	5.9
3	6.3	4.8	5.6	5.2
4	6.2	6.0	6.2	5.9
5	6.5	6.6	6.5	6.9
