Process time at a workstation is monitored using sample mean and range control charts. Six samples of seven observations have been obtained and the sample means and ranges computed $($in minutes$)$:Using the factors table below determine the upper and lower limits for sample mean and range control charts.In this question, you need to enter the value you calculated for the UPPER CONTROL LIMIT PLUS LOWER CONTROL LIMIT OF THE RANGE CHART $($UCL$-$ICL$).$SampleMeanRange$2\mathrm{.}980\mathrm{.}36-2........\mathrm{.}3\mathrm{.}050\mathrm{.}363........\mathrm{.}3\mathrm{.}010\mathrm{.}374..\mathrm{.}3\mathrm{.}070\mathrm{.}395\mathrm{.}2\mathrm{.}990\mathrm{.}376.\mathrm{.}3\mathrm{.}030\mathrm{.}37$A$2$D$3$D$421\mathrm{.}8803\mathrm{.}271\mathrm{.}022\mathrm{.}570\mathrm{.}7302\mathrm{.}2850\mathrm{.}582\mathrm{.}110\mathrm{.}4802\mathrm{.}0070\mathrm{.}420\mathrm{.}081\mathrm{.}9280\mathrm{.}370\mathrm{.}141\mathrm{.}860\mathrm{.}340\mathrm{.}181\mathrm{.}82100\mathrm{.}310\mathrm{.}221\mathrm{.}78110,290,261\mathrm{.}74$
