a$)$ Standard deviation of the sampling means $=$ ounces $($round your response to three ded

b$)$ With $z=3,$ the control limits for the mean chart are:

$UC{L}_{\stackrel{}{x}}={?}^{\text{p}\text{o}\text{u}\text{n}\text{c}\text{e}\text{s}(round\text{y}\text{o}\text{u}\text{r}\text{r}\text{e}\text{s}\text{p}\text{o}\text{n}\text{s}\text{e}to\text{t}\text{h}\text{r}\text{e}\text{e}\text{d}\text{e}\text{c}\text{i}\text{m}\text{a}\text{l}\text{p}\text{l}\text{a}\text{c}\text{e}\text{s}).}$

$LC{L}_{\stackrel{}{x}}=T_O$ounces $(round$ your response $to$ three decimal places$).$

c$)$ The control limits for the R$-$chart are:

$UC{L}_R=$dots 'ounces $(round$ your response $to$ three decimal places$).$

$LC{L}_R=$ ounces $(round$ your response $to$ three decimal places$).$

d$)$ 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$?$
