SCENARIO 6-5 Ball Bearings Are Manufactured with a Mean Diameter of 6

Short Answer

SCENARIO 6-5
Ball bearings are manufactured with a mean diameter of 6 millimeters (mm).Because of the inherent manufacturing process variability, the lots of bearings are approximately normally distributed with a standard deviation of 0.03 mm.
-Using Scenario 6-5 and the result of the previous question, if 40,000 ball bearings were to be manufactured, how many would the manager have to discard?
