An operator trainee is attempting to monitor a filling process that has an overall average of 705 cc. The average range is 17 cc. If you use a sample size of 6, what are the upper and lower control limits for the x-bar chart and R-chart?
What will be an ideal response?
From the table, A2 = 0.483, D4 = 2.004, D3 = 0
UCL = + A2 × LCL = - A2 × UCLR = D4 ×
= 705 + 0.483 × 17 = 705 - 0.483 × 17 = 2.004 × 17
= 713.211 = 696.789 = 34.068
LCLR = D3 ×
= 0 × 17
= 0
