Answer:
Process Capability ratio / Index = 0.133
Step-by-step explanation:
From the question, we are told:
Upper limit of 9.16 ounces
Lower limit of 9.12 ounces
Process width of 0.05 ounces.
what is the process capability ratio
Process Capability ratio or Index formula
= Cp = (USL - LSL)/(6 × Standard deviation)
Cp = 9.16 - 9.12/6 × 0.05
Cp = 0.04/0.3
Cp = 0.13333333333
Approximately = 0.133
