ICBB Online Practice Questions and Answers
What conclusion is most correct about the Experimental Design shown here with the response in the far right column?
A. No factor has enough statistical confidence greater than 95% to have an impact on the response rate
B. Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more
C. If the Adv is increased from the low level to the high level, the response rate increases
D. The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate
E. This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output
How many experimental runs exist in a Full Factorial and fully randomized design for 4 factors with 2 replicates for the Corner Points and no Center Points? The factors in the experiment are only at 2- levels.
A. 10
B. 32
C. 256
D. 64
If a Six Sigma project was to reduce repair station inventory and the team found the inventory was creeping up over time which Lean tools should be considered in the Control Phase to reestablish and sustain the project success?
A. Review the Visual Factory to assure inventory in excess of desired visible
B. Improve the lighting to assure adequate visibility
C. Analyze data from supplier deliveries
D. Reword the standardized work instructions to use active verbs and not passive phrases
Accuracy can be assessed in several ways and a fairly accurate means of measurement is visual comparison.
A. True
B. False
Which statements are correct about the advanced Capability Analysis shown here?
(Note: There are 3 correct answers).
A. This is a Poisson Capability Analysis.
B. The average DPU with 95% confidence is between 0.024 and 0.0295.
C. The DPU does not seem to vary depending on sample size.
D. The process shows only one instance of being out of control statistically so we have confidence in the estimated DPU of this process.
E. The maximum DPU in one observation was nearly 0.0753.
