5. Suppose that the company in problem 4 wishes to produce 10,000 parts that are within the specs (specifications) and that it operates the process centered at 1.500 centimeters.

a. How many parts should the company start so that it can expect 10,000 good parts to be completed?

b. What would be the cost of internal failure in this situation?
