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

If p<=0.05 then the effect is statistically Significant Insignificant Cant Say None of the above W What chart is used when sample size is 1

Some difference exists between 2 samples No difference exists Difference may or may not exist None of the above What is a defect? Something which will always happen A feeling that the process is causing a problem A measurable indicator not conforming to customer requirement All of the above What is the standard deviation of the following population 11,13,18,15,9 3.49 3.12 3 4 What type of DOE is used if there are 5 or more factors Screening DOE Optimization DOE Characterization DOE All of the above When a point on the graph falls outside the control limits without a special cause it can be classified as a Type I error Type II error This is natural Cant say Which formula is used to calculate the correlation RSQ CORREL CORELATION None of the above Which graph reveals relationships or association between two variables Scatter Plot Box Plot Frequency Plot Interval Plot Which is a low cost VOC tool
