Determine the RTY.
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.
