calculate UCLr and LCLr Rchart

A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (eac 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 UCLx=LCLx=ounces(roundyourresponsetothreedecimalplaces)ounces(roundyourresponsetothreedecimalplaces). c) The control limits for the R-chart are UCLR=ounces(roundyourresponsetothreedecimalplaces)
