Relet to Jabie $$61.$ Eactors for Computing Control Chart Limits $(3$ sigma$)$ for this problem.

a$)$ For the gven sample size, the control limits for $3-$sigma $\stackrel{}{x}$ chart are:

thper Centrot limit $($UCL$-{?}_x)=$ Ib $($round your response to three decimal places$).$

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

h$)$ The control limits for the $3-$sigma $R-$chart are:

Upper Control Limi $(UC{L}_R)=$

b$.($round your response to three decimal places$),$

Lower Control $($imit $(LC{l}_R)=$

b$.($round your response to three decimal places$).$
