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 1.36. 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: UCLx= ounces (round your response to three decimal places)
