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 1.36. 1 2 4 7 8 9 10 13 12 10 9 9 9 13 11 13 13 12 3 13 10 9 10 8 11 11 10 11 10 Samples 5 6 13 9 9 9 10 7 11 11 9 9 10 10 10 8 8 10 7 9 7 9 7 11 12 10 10 12 10 9 11 a) Standard deviation of the sampling means = ounces (round your response to three decimal places). 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- = 12.539 ounces (round your response to three decimal places). LCL = 8. 141 ounces (round your response to three decimal places). c) The control limits for the R-chart are: UCLR = 8.672 ounces (round your response to three decimal places). LCLR = 0.000 ounces (round your response to three decimal places). d) Based on the x-chart, is one or more samples beyond the control limits? No Based on the R-chart, is one or more samples beyond the control limits? No
