ICGB Exam - Question 27

Question

Select all the statements that are true after reviewing the Capability Analysis shown here. (Note: There are 4 correct answers).

Examice · Accepted Answer

The process is out of control as evidenced by the I Chart where several points exceed control limits. The process can be assumed to be normal based on the Normal Probability Plot which aligns well with the fitted line. The mean of the process moving range is indeed 1.78 as indicated on the Moving Range Chart. This Capability Analysis seems not to use subgroups as shown in the I Chart which plots individual values rather than subgroup averages.
