Problem $3$

Ten samples with five observations each have been taken from the Crunchy Potato Chip Company plant in order to test for volume dispersion in the bagging process. The average sample range was found to be $0\mathrm{.}3$ ounces. Develop control limits for the sample range.

$$ Before You Begin:

To compute the control limits for the sample range, remem$-$ ber to look up the values for D$4$ and D$3$ from Table $6-1$ for the appropriate value of n$.$ In this problem n $5.$
