Explanation / Answer

1) UCL = 1.2

LCL = 0.9

Mean = 1

SD = 0.2

Process is not centered, so Process capability = Min((UCL-Mean)/(3*SD), (Mean-LCL)/(3*SD))

= Min((1.2-1)/(3*0.2), (1-0.9)/(3*0.2)) = Min(0.33,0.16) = 0.16

Ans A

2) C

It plots the value of sample means for each sample to check whether values are between UCL & LCL

3) D

The Normal causes of variation are those which are routine but assigned causes of variation are non-routine and must be controlled

4) C

It will comply to 6 sigma definition of 99.73% level
