A precision parts manufacturer produces bolts for use in the construction of military aircraft. The specification for the bolt length is 37.5 ± 0.2 cm. The manufacturing process for this item is currently in a state of statistical control with a process mean of 37.575 cm. A new contract has been constructed that requires that bolt manufacturing process maintain a minimum capability of 1.33. What is the maximum variability in the process that can be permitted if this process is to meet this capability requirement given the current process mean?
