Question

a specification for bottle filling has an upper limit of 9.16 ounces and a lower limit of 9.12 ounces. the process is stabilized and centered at the specification mean, with a process width of 0.05 ounces. what is the process capability ratio

Answer 1

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
