Refer to Table $6.1-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.

LCL; ounces (round your response to three decimal places). c) The control limits for the R-chart are UCLR LCL ounces (round your response to three decimal places). 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?
