Sampling $4$ pieces $of$ precision$-$cut wire $(tobe$ used $in$ computer assembly$)$ every hour for the past $24$ hours has produced the following results:

Based $on$ the sampling done, the control $limits$ for $3-$sigma $\stackrel{}{x}chart$ are $(round$ all intermediate calculations $to$ three decimal places before proceeding with further calculations$)$:

Upper Control Limit $(UC{L}_{\frac{?}{\text{b}\text{a}\text{r}}()})=,$ inches $(round$ your response $to$ three decimal places$).$

Lower Control Limit $(LC{L}_{\stackrel{}{x}})=,$ inches $(round$ your response $to$ three decimal places$).$

Based $on$ the $\stackrel{}{x}-$chart, the wire cutting process has been

The control $limits$ for the $3-$sigma $R-$chart are $(round$ all intermediate calculations $to$ three decimal places before proceeding with further calculations$)$:

Upper Control Limit $(UC{L}_R)=,$ inches $(round$ your response $to$ three decimal places$).$

Lower Control Limit $(LC{L}_R)=,$ inches $(round$ your response $to$ three decimal places$).$

Based $on$ the $R-$chart, the wire cutting process has beer
