Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. A process that 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 1.38. 1 3 10 2 11 9 9 11 12 9 8 11 10 13 10 11 12 11 Samples 4 5 6 7 8 9 12 11 10 12 10 9 11 11 16 11 8 7 11 8 10 10 11 9 9 11 9 10 9 7 14 10 10 9 10 9 11 12 9 10 9 12 a) Standard deviation of the sampling means = ounces (round your response to three decimal places). b) With z = 3, the control limits for the mean chart are: UCL; -ounces (round your response to three decimal places). LCL-ounces (round your response to three decimal places). c) The control limits for the R-chart are: UCLR-ounces (round your response to three decimal places). LCLR-ounces (round your response to three decimal places). d) Based on the x-chart, is one or more samples beyond the control limits? Based on the R-chart, is one or more samples beyond the control limits?
