wash process is advertised to take less than $7$ minutes. Consequently, management has set a target average of $400$ seconds for the wash process. Suppose the average range for a sample of $10$ cars is $8$ seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process.Click the icon to view the table of factors for calculating three$-$sigma limits for the X$-$chart and R$-$chart.The UCL equalsseconds and the LCL equalsseconds. $($Enter your responses rounded to two decimal places.$)-$ XMore InfoFactors for calculating three$-$sigma limits for the x$-$chartand R$-$chartSize ofSample $($n$)$Factor for UCL and LCLfor x$-$chart $($A$,)$Factor for LCL for R$-$Chart $($D$3)$Factor for UCL for R$-$Chart $($Da$)21\mathrm{.}8803\mathrm{.}26731\mathrm{.}02302\mathrm{.}57540\mathrm{.}7292\mathrm{.}28250\mathrm{.}57702\mathrm{.}11560\mathrm{.}4832\mathrm{.}00470\mathrm{.}4190\mathrm{.}0761\mathrm{.}92480\mathrm{.}3730\mathrm{.}1361\mathrm{.}8640\mathrm{.}3370\mathrm{.}1841\mathrm{.}816100\mathrm{.}3080\mathrm{.}2231\mathrm{.}777$
