Specification limits for a particular characteristic of a product indicate the values at which the product will operate properly. Assume we have a product with an upper specification limit of 7.25 and a lower specification limit of 4.0. As long as our product falls within these limits our buyers will be happy. We now investigate the process used to manufacture the product and find that the process (population) mean is 5 and the process (population) standard deviation is 0.5. Assuming the process is normally distributed, what percentage of items will fall outside the specification limits?
