Thirty samples of size $3$ resulted in an overall mean of $16\mathrm{.}42$ and an average range of $1\mathrm{.}94.$ Compute control limits for $\stackrel{}{x}-$ and $R-$charts. Use the control char factors in Appendix B to answer the questions. If your answer is zero, enter $"0".$ Round your answers to three decimal places.

For the $R-$chart:

$$

$LC{L}_R$ : $$

For the $\stackrel{}{x}-$chart:
