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 process standard deviation is 1.20 a) Standard deviation of the sampling means =0.537 ounces (round your response to three decimal places) b) With z=3, the control limits for the mean chart are UULx^=11.871 ounces (round your response to three decimal places) LCLx=8.320 ounces (round your response to three decimal places). c) The control limits for the R-chart are ULR=7.188 ounces (round your response to three decimal places). LCLR=0.00 ounces (round your response to three decimal places) d) Based on the x-chart, is one or more samples beyond the control limits
