A process produces a certain part with a mean diameter of 3 inches and a standard deviation of 0.05 inches. The lower and upper engineering specification limits are 1.80 inches and 3.05 inches. What is the Cp (measure of potential capability)

Respuesta :

Answer:

The correct answer is 4.167

Step-by-step explanation:

According to the given scenario, the calculation of the Cp i.e. measure of potential capability is as follows;

= (USL - LSL) ÷ 6 × standard deviation

= (3.05 inches - 1.80 inches) ÷ 6 × 0.05

= 1.25 ÷ 0.3

= 4.167

hence, the calculation of the Cp i.e. measure of potential capability is 4.167
