3 points Sar Process time at a workstation is monitored using sample mean and range control charts. Six samples with 10 observations each have been obtained and the sample means and ranges computed (in minutes) as follows: Sample 12 15 Mean Range 4.6 0.68 4.32 052 442 0.64 46 454 HA 62 0.78 What are the upper and lower limits for sample range control chart?
