b) With z = 3, the control limits for the mean chart are: UCL Subscript x overbar = ____(round your response to three decimal places). LCL Subscript x overbar = _____(round your response to three decimal places). c) The control limits for the R-chart are: UCL Subscript Upper R = _____(round your response to three decimal places). LCL Subscript Upper R = _____(round your response to three decimal places). d) Based on the x overbar-chart, is one or more samples beyond the control limits? Yes or no? Based on the R-chart, is one or more samples beyond the control limits? Yes or no?

Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (each of size n = 5) taken. The population process standard deviation is 1.64. 1 2 3 4 8 9 13 9 11 12 9 8 11 10 10 9 11 Samples 5 6 12 10 9 9 8 7 10 11 11 8 14 12 12 13 11 11 10 9 13 9 7 13 8 12 11 7 10 8 9 11 11 9 11 11 9 11 9 8 7 a) Standard deviation of the sampling means = 0.733 ounces (round your response to three decimal places). b) With z = 3, the control limits for the mean chart are: UCL; = = 13.099 ounces (round our response to three decimal places)
