A company has been monitoring a process at one of its work centers over the last week. A range chart was developed that had LCLR $=0$ and UCLR $=3\mathrm{.}4.$ Similarly, a mean chart was developed that had $.$ The process was in control. Yesterday, five samples of size $4$ were taken from the process. The ranges for each of the five samples were $1\mathrm{.}25,2\mathrm{.}02,2\mathrm{.}65,2\mathrm{.}55,$ and $2\mathrm{.}70,$ respectively. The values of the sample average for each sample were $18\mathrm{.}5,22\mathrm{.}3,17\mathrm{.}4,20\mathrm{.}1,$ and $19\mathrm{.}9,$ respectively. What can you tell management based on this new data? Provide any documentation $($charts$)$ needed to support your analysis here. $($Note that you do not need to recalculate control limits$.)$
