The diameter of a part has to fit an assembly. The specifications for the diameter are 540.015cm. Samples taken from the process in control yielded a sample mean (X o 4.99cm and sample standard deviation (s) of 0.004cm. The upper process capability limit (UNTL) and lower process capability limit (LNTL) based on the sample estimates are f to be 5.002em and 4,978cm.
