Refer to Table S6.1 - 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 pre standard deviation is 1.20. Samples 5 6 4 7 8 10 13 9 13 12 12 13 9 9 9 10 12 10 10 8 8 13 8 9 10 7 8 13 9 12 10 9 12 8 12 9 11 8 7 12 7 10 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). 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?
