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 = 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? Enter your answer in each of the answer boxes.
