Why 6s is associated with 3.4 dpmo?

11. Short Answer – 2
Many manufacturing problems involve the accurate matching of machine parts such as shafts that fit into a valve hole. A particular design requires a shaft with a diameter of mm, but shafts with diameters between mm and mm are acceptable. Suppose that the manufacturing process yields shafts with diameters normally distributed with a mean of mm and a standard deviation of .005 mm. If a random sample of 36 shafts is chosen from the above process, what is the probability of the sample mean being above mm?
