Find the C_p index for a process with USL = 550, LSL = 540, μ = 545, and σ = 0.75. A)1.25 B)1.33 C)2.22 D)1.75

Question

Quizplus · Accepted Answer

The C_p index is calculated using the formula: C_p = (USL - μ)/(3σ) + (μ - LSL)/(3σ) Substituting the given values, we get: C_p = (550 - 545)/(3*0.75) + (545 - 540)/(3*0.75) = 5/2.25 + 5/2.25 = 10/2.25 = 4.44 Since the C_p index should be less than or equal to 1 to indicate a capable process, the given process is not capable. Therefore, the best choice is C, which is the only option greater than 1.
