Hi. I am using windows xp. I tried to install mercury quality center using evaluation key. I got an error in advance database server configuration. Pls anyone help me to sort out this issue.
Skill/topic: statistical process controla) noise variable factors EIther cannot be controlled or are difficult and or expensive to control during the design or actual production stage.
Noise Factors are factors which cannt be eliminated . Its better to minimize the effect of noise factors bcoz trying to eliminate it is a complete waste as it will take more time and more cost.
Noise variable factors either cannot be controlled or are difficult and or expensive to control during the design or actual production stage.
A stable process still has a ________________
Skill/topic: statistical process controla) variationexplanation: even though the process may be stable, it will still have variation. This variation could be due to common causes.
Common cause variations
A) Variation
Skill/topic: statistical process controla) p chartb) x bar chartc) C chartd) r chart
X Bar chart
D) R Chart
Skill/topic: statistical process controla) it is used to monitor the number of defects per unit
C chart is used when sample size is constant (say 1 ) and no of defects varies.....
For eg : No of defects in A4 size paper , 25 samples of A4 papers are taken. Here sample size is 1 for all the samples.
At the time of failures in the Process
Skill/topic: statistical process controla) 99.73%b) 99.99%c) 99.10%d) 99.78%
For +/- 3 sigma process its 99.73 % and for +/- 6 sigma process its 99.9997%
99.10%

Variability
B. Variability
Each measurement has an error associated with it
Skill/topic: statistical process controla) trueb) false
True
A) True
Doe does not improve the process yields
Skill/topic: statistical process controla) trueb) falseexplanation: apart from improving the capability of a process, doe also increases the process yields
True: Design of Experiment allows the most impactful parameters to hopefully be identified and enable the experimenter to target improvements in a more fruitful and effective manner. The DOE is a diagnostic tool - not the repair.
A) True
