A. If the process capability ratio of a centered process is 1.25, and the process mean is 240, what is the average amount of defects per 1 million outputs?
B. A pasta manufacturing process has a lower specification limit of 15.9 oz. and an upper specification limit of 16.2 oz. The standard deviation is 0.03 oz., and the average is 16 oz. What is the process capability index Cpk for the process? (note: please follow the definition of the process capability index in the lecture note)
C. A cookie shop makes cookies with an average weight per bag = 1 lb. The process has a standard deviation of 0.012 lb. The upper and lower specification limits are 1.02 lb and 0.98 lb, respectively. What is the probability that a bag of cookies will either be too heavy or too light?
