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:

$UC{L}_{\stackrel{}{x}}=6\mathrm{.}84,LC{L}_{\stackrel{}{x}}=6\mathrm{.}26$

$UC{L}_R=0\mathrm{.}958,LC{L}_R=0.$

Over the past few days, they have taken five random samples of four loaves each and have found the following:

$\backslash$table$[[,$Net Weight$],[$Sample$,$Loaf # $1,$Loaf # $2,$Loaf # $3,$Loaf# $4],[1,7\mathrm{.}0,6\mathrm{.}9,6\mathrm{.}7,6\mathrm{.}6],[2,6\mathrm{.}5,6\mathrm{.}5,6\mathrm{.}4,6\mathrm{.}4],[3,6\mathrm{.}6,6\mathrm{.}5,6\mathrm{.}2,6\mathrm{.}5],[4,6\mathrm{.}4,6\mathrm{.}6,6\mathrm{.}4,6\mathrm{.}2],[5,6\mathrm{.}6,6\mathrm{.}5,6\mathrm{.}4,6\mathrm{.}7]]$

Based on the $\stackrel{}{x}-$chart, is one or more samples beyond the control limits$?$

Based on the R$-$chart, is one or more samples beyond the control limits$?$
