Factors for computing control chart limits (3 sigma) for this problem

Cordelia Barrera is attempting to monitor a filling process that has an overall average of 715 cm3
The average range R is 6 cm3
For a sample size of 10 the control limits for 3-sigma x-bar chart are:

Upper Control Limit (UCL x-bar) = ____ cm3 (round to 3 decimals)
Lower Control Limit (LCL x-bar) = _____ cm3 (round to 3 decimals)

The control limits for the 3-sigma R-chart are:

Upper Control Limit (UCL R) = ____ cm3 ( round to 3 decimals)
Lower Control Limit (LCL R) = ____ cm3 ( round to 3 decimals)
