Number of packets in a box (n) = 8
Average range in the weight of each sample (R bar) = 7 grams
The average weight of each packet (X double bar) = 41 grams
Now using the above table,
For the size of sample n = 8,
A2 = 0.373
D3 = 0.136
D4 = 1.864
Ans a)
For R chart
Control limit = R bar = 7 grams
Upper Control Limit (UCLR) = D4* Rbar
= 1.864 * 7
= 13.05 grams
Lower Control Limit (LCLR) = D3* Rbar
= 0.136 * 7
= 0.95 grams
