In process capability analysis, the indices Cp and Cpk are commonly used to evaluate how well a process can produce output within specification limits. These metrics help assess both the spread and the centering of a process in relation to its specifications. Which of the following statements istrueregarding process capability indices?Question 14 options:A Cpk value of 1 is ideal, meaning all units meet specifications.The larger the Cpk, the greater the proportion of units that meet specifications.The value of Cp is always less than or equal to the value of Cpk.Cpk can only be used when the process centerline matches the specification centerline.The value of Cp increases as the process becomes more centered to the target.
