Factors of Computing Control Chart Limits (3 sigma) Table for the problem above

Refer to Table $6.1- Factors for Comauting Control Chart Limits t3 siama for Ros Hopkin s atempago ng process that has an overal verage of 715 ce. Thae Refer to Table S6.1 -Factors for Computing Control Chart Limits (3 sigma) for this problem. Ross Hopkins is attempting to monitor a filling process that has an overall average of 715 cc. The 3 average range R is 6 cc average range R IS 6 CC For a sample size of 10, the control limits for 3-sigma x chart are: Upper Control Limit (UCL-,- cc3 (round your response to three decimal places).

Explanation / Answer

mean=m=715

Range mean=R=6

for sample sie of 10, A2=0.308

UCL=m+A2*R=715+0.308*6=716.848

LCL=m-A2R=715-0.308*6=713.152
