HS 7.3(a) Is this process in a state of statistical control? Why? There are five observations for each day, the mean chart and the range chart will be use.
Overall: = 0.507523 = .000183
Mean Chart:
| 0.507523 | UCL | 0.507628591 | LCL | 0.507417409 |
Mention: the 17th point is below the lower control limit
Range Chart: | 0.000183 | UCL | 0.000386928 | LCL | 0* |
* LCL=-0.000021 LCL=0
(b) What recommendations should be made about improving the process?
We need to determine why the 17th point in mean chart out of the LCL.
Phase 3 After conducting research on the cam, Natalie analyze the graphs, which showed that on 17
