S$6\mathrm{.}9$ Organic Grains LLC uses statistical process control to ensure that its health$-$conscious, low$-$fat, multigrain sandwich loaves have the proper weight. Based on a previously stable and in$-$control process, the control limits of the $\stackrel{}{x}-$ and $R-$charts are $UC{L}_{\stackrel{}{x}}=6\mathrm{.}56.LC{L}_{\stackrel{}{x}}=5\mathrm{.}84,UC{L}_R=1\mathrm{.}141,LC{L}_R=0.$ Over the past few days, they have taken five random samples of four loaves each and have found the following:

$\backslash$table$[[$SAMPLE$,$NET WEIGHT$],[$LOAF #$1,$LOAF #$2,$LOAF #$3,$LOAF #$4],[1,6\mathrm{.}3,6\mathrm{.}0,5\mathrm{.}9,5\mathrm{.}9],[2,6\mathrm{.}0,6\mathrm{.}0,6\mathrm{.}3,5\mathrm{.}9],[3,6\mathrm{.}3,4\mathrm{.}8,5\mathrm{.}6,5\mathrm{.}2],[4,6\mathrm{.}2,6\mathrm{.}0,6\mathrm{.}2,5\mathrm{.}9],[5,6\mathrm{.}5,6\mathrm{.}6,6\mathrm{.}5,6\mathrm{.}9]]$

Is the process still in control? Explain why or why not.
