At Isogen Pharmaceuticals, the filling process for its asthma inhaler is set to dispense 150 milliliters (ml) of steroid solution per container. The average range for a sample of 4 containers is 3 ml. The lower control limit for the mean chart, rounded to three decimal places, is ……….. milliliters.
Homework Answers
Solution:
Mean (X-bar) = 150 ml
Average range (R-bar) = 3 ml
Sample size (n) = 4 containers
From the table of factors for computing control chart limits (3-sigma),
for n = 4 (sample size = 4),
A2 = 0.729
The Lower Control Limit (LCL) for the mean chart is calculated as,
LCL = X-bar - (A2 x R-bar)
LCL = 150 - (0.729 x 3)
LCL = 147.813 millilitres

An automatic lathe produces rollers for roller bearings, and the process is monitored by statistical process control charts. The central line of the chart for the sample means is set at 8.40 and for the mean range at 0.3 mm. The process is in control, as established by samples of size 5. The upper and lower specifications for the diameter of the rollers are (8.40 + 0.25) and (8.40 -0.25) mm, respectively. Click the icon to view the table of...
