Answer:
1.33
Step-by-step 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:
[tex]C_P = \dfrac{USL -LSL}{6 \times \sigma}[/tex]
[tex]C_P = \dfrac{10 -2}{6 \times 1}[/tex]
[tex]C_P = \dfrac{8}{6}[/tex]
[tex]C_P = \dfrac{4}{3}[/tex]
[tex]C_P =1.33[/tex]
