Question

"Brad is trying to determine the Cp of a process. The USL is 10, the LSL is 2, and the standard deviation is 1. What is the Cp"

Answer 1

1.33

Explanation:

Given that:

Upper specification limit ( USL ) = 10

Lower specification limit ( LSL ) = 2

the standard deviation σ = 1

What is the Cp"

The Cp is the process capability ratio which can be expressed by the formula:

`C_P = (USL -LSL)/(6 * \sigma)`

`C_P = (10 -2)/(6 * 1)`

`C_P = (8)/(6)`

`C_P = (4)/(3)`

`C_P =1.33`
