Six sigma questions

Below are possible questions for a Six sigma exam. How many data points do you need to have a short-term capability? Two data points. Over 100 data points. Fewer than five data points. Between 30 and 50 data points. If the Cp is 1.0, what is the sigma value? 1 2 3 6 None of above

What is the purpose for gauge R&R? Statistical analysis to evaluate measure error To understand repeatability and reproducibility of your MSA To help validate what is a defect and what is not To gauge the rest and relaxation needed for a black belt a through d Q4. What plot describes the many distributions in one graph in quartiles? Interval plot Capability plot Probability plot Median plot Box plot Q5. What is meant by a p-value of less than 0.05? That there are no significant difference The variance terms are equal The mean has a shift of 1.5 sigma You're 95 percent confident that there is a statistical difference All the above A correlation value of less than 0.2 indicates Significant correlation Insignificant Correlation Cant Say None of the above

An activity in a process map is represented using a Circle Triangle Rectangle Cylinder As per the RACI model the sponsor or champion is assigned what role R A C I At 5 sigma DPMO equals 6210 233 3.4 None of the above At what percentage are Gage R&R test unsatisfactory 10% 15% 25% >30% Average companies operate at what sigma levels 3Sigma 4Sigma 5Sigma 6Sigma Can the process owner and champion be the same person Yes No Cant Say None of the above Cp is a capability index with the units measured in? mm No units Scale of 1 to 5 Defect rate or yield

If Cpk = Process Process Process Process

Cp, this result means that themean is on target mean is not on target mean can not be defined mean is defected
