Question
of 2.0 represents how many Standard Deviations of Coverage? b) What percent of the Population would it cover? 28) All else being equal, Opening up the Specifications will increase a Cpk True False 29) All else being equal, Opening up the Specifications is the BEST way to increase a Cpk True False 30) If Warren Buffett made an ADDITIONAL $40 Bilion this year,it would move US Mean Income up, but only slightly: True False 31) In a Normal or Bell Curve, the Mean has the Largest sample population False True 32) Cpk is not only a measure of Manufacturing Capability, but it is a measure of how close production is to Design Tolerances: True False 33) 1s Large Variations in independent production machinery good or bad? Can the size of the Buffers between them have a help in smoothing out these fluctuations? What if the buffers are too small? Please Explain.Explanation / Answer
Question 27
(a) Here CPk is two then it will give a coverage of 12 sigma or say 12 times of standard deviation.
(b) It would cover a population of 99.99999980 % of population
Question 28
Opening up the specification wil increase the Cpk as it is proportional too difference between control limits.
Queston 29 No decrasing the standard deviation is the best method.
Question 30
Yes, it would increase the mean but it will be very slight movement in the mean.
Question 31
In normal bell curve, mean has the largest population. It is yes statement as mean and mode are same here.
Question 32
Yes, the given statement is true here.
Question 33
Large variations in independent production machinary is not good here. A depleting size of buffers signficantly help to smoothing out the fluctuations in machinary. Too small buffers are not of much help. Standardized buffers could help to even out the large variations in the production machinary.
