After getting a process into statistical control,

$1)$ A Range chart was developed $(3-$sigma limits$)$ with LCL$=0$ and UCL$=2\mathrm{.}50.$

$2)$ Similarly an X$-$bar chart was developed $(3$ sigma limits$)$ with LCL$=15$ and UCL$=24.$

Five monitoring samples subsequently taken read as follows:

a$)$ sample ranges: $0\mathrm{.}75,2\mathrm{.}42,1\mathrm{.}82,2\mathrm{.}04,2\mathrm{.}65,$ and

b$)$ sample means: $19\mathrm{.}5,22\mathrm{.}3,16\mathrm{.}55,20\mathrm{.}1,23,$ respectively.

What can you tell management from this analysis?
