A process has a C_p equal to 3.5.Determine the standard deviation of the process if the design specifications are 16.08 inches plus or minus 0.42 inches. A)0.02 B)0.04 C)0.21 D)0.84

Question

Quizplus · Accepted Answer

The process capability index C_p is calculated as (USL - LSL) / (6 * σ). Here, USL = 16.08 + 0.42 = 16.50 and LSL = 16.08 - 0.42 = 15.66. So, C_p = (16.50 - 15.66) / (6 * σ) = 3.5. Solving for σ gives σ = 0.04.
