QUESTION 1 (30 points: 10 points each) A process has demonstrated that, when held in control, it can maintain a o of 0.20 cm. A certain part has specifications of 15.00 +0.59cm. Using a target of 15.00 cm, find control limits for Xbar and R charts based on a subgroup of 7 units. 1. What proportion of units would you expect to not meet specifications, assuming that the process generates an approximately normal distribution of measurements? 2. Mean was shifted to 14.80. What is the probability that the next point of value of Xbar will fall within the control limits (the probability of Type Il error), 3. Mean was shifted to 14.80. What proportion of units would you expect to not meet specifications, assuming that the process generates an approximately normal distribution of measurements ?
