Question 1: A product must measure 10 ±0.5 cm. If the process has a standard deviation of 0.13, what is the sigma-rating of the process? (Round your answer to TWO places of decimal)
Question 2: What fraction of product is defective for a 2.88-sigma process? Express your answer in percentage, rounded to TWO places of decimal.
Question 3: A manufacture produces 16 oz bread loaves that must measure within the the specification 16±1.64 oz. If the manufacture sets its goal to at least attain 3-σ quality rating, what is the maximum process standard deviation it will allow itself? (Enter ONLY numerical values, and round your answer to TWO decimal places)
Question 4: A manufacturer is known to have a 3.7-process. |
Fraction defective = P(ZZ(UTL)). Based on the sigma-rating what is the value of Z(LTL)?
Question 5: A manufacturing process has a 3.71-sigma quality. What fraction of its product is defective? Express your answer in DPMO, rounded to the nearest INTEGER.
