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:

UCLx = 5.78, LCLx = 5.42;

UCLR = 0.301, 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
1	5.9	5.8	5.8	5.6
2	5.4	5.8	5.5	5.8
3	5.6	5.5	5.3	5.6
4	5.5	5.7	5.5	5.7
5	5.4	5.6	5.7	5.4

A) Based on X bar chart, is one or more samples beyond the control limit? Yes or No

B) Based on R-chart, is one or more sample beyond the control limit? Yes or No
