1. A process consists of three sequential steps with the following yields: Y1=99.8, Y2=97.4, Y3=96.4 1. Determine the RTY. 2. What is Z bench? 2. One thousand units of a product were examined for the possibility of 5 different undesirable characteristics. A total of 80 defects were found. How many defects would be expected in a million opportunities? 3. The outside diameter of a part used in a gear assembly is known to be normally distributed with a mean of 39 mm and a standard deviation of 2.5 mm. The specifications on the diameter are (36, 45), which means that part diameters between 36 mm and 45 mm are considered acceptable. 1. What is the proportion nonconforming? 2. What is Z bench? 3. If the mean of the process was centered between the specs, what would the proportion non-conforming be
