Operators at the final stage of the syringe assembly process chose 35 consecutive observations for a capability study and arrived at an estimated minimum process capability index of:
A)1.01.
B)0.97.
C)1.03.
D)0.99.

Question

Quizplus · Accepted Answer

The estimated minimum process capability index is 1.03, which suggests that the process is capable of producing products within the required specifications with very little variation. This is a desirable outcome and the operators should continue with the current assembly process. The other choices are not the best because they either suggest that the process is barely meeting the requirements (choice A and D) or that there is some room for improvement (choice B).
