Lean Six Sigma Green Belt Sample Paper 2: Analyze This sample paper will check your knowledge on Analyze phase for LSS Green Belt Click on 'Next' to start 1. Analysis of variance (ANOVA) comparesTwo population standard deviationsTwo population variancesTwo population proportionsNone of the above2. Which of the following is TRUE?Causes in fishbone must be bucketed into categories starting with the same alphabet. E.g. 6M, 4P, 4S, etc.Affinity diagram and fishbone diagram can be used to list potential causesIn affinity diagram the first task is to create categories in which causes having some commonality can be grouped post brainstormingIshikawa diagram is another name for Affinity diagram3. In a Pareto plot, what is represented on the secondary Y axis?% contributionFrequency% cumulative contributionSeverity4. FMEA can be used forTo identify critical causesTo evaluate solutions for implementationFor risk assessmentAll the above5. Value adding step in a process is something:Customer is willing to pay forTransforms the product/serviceEssential to be done right the first timeAll the above6. Which one of the following is FALSE?P-value is compared to alpha which is always fixed at 0.05P-value cannot be more than 1If P-value is less the alpha, then alternate hypothesis is acceptedP-value cannot be less than 07. Which one of the following is NOT TRUE?Higher the RPN, higher the riskHigher detection rank means poor ability to detectHigher severity rank indicates high riskImproving detection reduces occurrence8. Which of the following is NOT a statistical approach in identifying critical X’s?Chi-square testVA/NVA Analysis2 proportion testLinear regression9. All the following are graphical tools, EXCEPTPareto plotBox plotScatter plotFailure Mode and Effects Analysis10. Which of the following will help generate a list of potential causes?Fishbone diagramAffinity diagramCause and effect diagramAll the above11. Pareto will only list issues which have occurred in the past, while FMEA will also list potential failures that have no history of occurrence. This makes the former a ______tool.ProactiveBetterReactiveMore reliable12. If alpha is 0.05, then significance level is0.9595%0.050.513. PFMEA stands forPotential failure mode and effective analysisProcess failure mode and effects analysisProbable failure mode and effects analysisPotential failure means and effects analysis14. Which of the following statements about Scatter plot is TRUE?A negative correlation is a sure sign of a non-critical input (X)Scatter plot can only be made for Discrete dataA high correlation does not imply causationNone of the above15. XYZ company wants to know whether the proportion of customers opening an e-mail increases if the customer’s name is mentioned in the title. % mails opened with name in title is to be compared with % mails opened without name in the title. What is the appropriate test for the above objective?2-Sample t test2-Proportion testChi-Square testCorrelationTime is Up!
