Unformatted text preview: b. What does this figure tell you about the process? 2 3. The nominal value of a light-bulb production process is 1,000 hours, with an upper specification limit of 1,240 hours and a lower specification limit of 760 hours. Investigation on two companys light-bulb production processes reveal that both have processes that are centered, but one company maintains 6-sigma quality and the other maintains 4-sigma quality. Draw the product distributions of the two companys processes. 3...
