Lean Six Sigma Green Belt Sample Paper: Measure 1. The specifications for Room temperature is as follows: USL = 24, LSL=18, Process Average =22 and standard deviation is 1. What is the Zlt? 3 5 4 22. 2000 forms were inspected, 127 forms were incomplete and therefore considereddefective. What is Zlt? 2.53 1.53 1.03 2.633. 1000 projectors were inspected. 64 defects were observed. Consider OFE unknown. What is Zlt? 1.64 1.73 1.24 1.544. For diameter of a ball, the Cp is .75, and Cpk is 0.75. We wish to improve the capability of the process. What should we do? Move mean closer to target Reduce variation Both ‘a’ and ‘b’ None of the above5. The FTY yield of four sub‐processes is 99%, 98%, 99% and 97%. What are the RTY and Zlt? RTY =94.63% and Zlt=1.61 RTY =93.63% and Zlt=1.52 RTY =94.17% and Zlt=1.57 RTY =93.17% and Zlt=1.496. The average delivery time of a product = 22,standard deviation=6, what is the expected DPMO if the delivery is desired within 30 minutes? (Assume delivery time follows normal distribution) 90143 85243 91211 881567. A mobile phone can have up to 5 defects. 200 mobile phones were inspected and 56 defects were observed. What is Zlt? 1.59 1.61 1.63 1.568. The main deliverable of Measure Phase is Identify the Project Evaluate current performance Control Plan Train the Process Owner9. The diameter of a component should be 8mm+‐2. The average diameter is 7 and standard deviation (within) is 1. What is Cp, Cpk? Cp=.67, Cpk=.33 Cp=1.67, Cpk=1.33 Cp=1.33, Cpk=1 Cp=2, Cpk=210. An improvement manager collects a product every 30 minutes for testing. What sampling method did the improvement manager use? Random Sampling Stratified Sampling Systematic Sampling Homogenous Sampling11. Appraiser A agrees with him/herself, Appraiser B him/herself across trials, Appraiser A & B don’t agree with each other. What primary error is it? Reproducibility Repeatability Appraiser Accuracy Stability12. Which of the following statement is not true? Appraiser Repeatability can be more than Team Reproducibility Team Reproducibility can be more than Team Accuracy Team Reproducibility can be equal to Team Accuracy Appraiser Repeatability can be less than Team Reproducibility13. If Zlt =3, what is DPMO = 1349 13499 66807 679814. Central Limit Theorem states that, for large values of n, the distribution of the sample________ will converge to a normal distribution even though the random variable x (individual data points) may be non‐normal Mean Sum Both ‘a’ and ‘b’ None of the above15. Specification limit is Maximum value in the collected data Minimum value in the collected data Both ‘a’ and ‘b’ Specified/stated by the customer16. Which of the following data type is classified as continuous? Defective (Yes/No) Weight of the cricket ball Types of Ice‐Cream Number of No Balls bowled by a bowler
