Problem:
Linda Boardman, Inc., an equipment manufacturer in Boston, has submitted a sample cutoff valve to improve your manufacturing process. Your process engineering department has conducted experiments and found that the valve has a mean (mu) of 12.00 and a standard deviation (sigma) of 0.04. Your desired performance is mu = 12.00 +/- 3 standard deviations, where sigma is 0.020.
Required:
Question 1) What is the process capability index?
a) 0.100
b) 0.300
c) 0.500
d) 0.700
e) 0.900
Solve the problem and show all work.
