A c chart is used to monitor the number of surface imperfections on sheets of photographic film. The chart presently is set based one of 2.4 (30 pts) a) Find 3-sigma control limits for this process. b) Use Poisson Table to determine the probability that a point will fall outside these control limits while the process is actually operating at a u, of 2.4. c) If the process average shifts to 3.2, what is the probability of not detecting the shift on the first sample taken after the shift occurs? 3. Control charts for X and R are maintained on the shear strength in pounds of test spot welds. The subgroup size is 8. The values of X and R are computed for each subgroup. After 20 subgroups, ΣX = 14,076 and ΣR = 1,982. (20 pts) a) compute the value of the 3-sigma (30) for the X and R charts and estimate the value of on the assumption that the process is in statistical control. b) The specified strength for a weld is 628 lb. If the process is in statistical control and normally distributed, what can you conclude regarding its ability to meet this specification?
