six sigma gives wide range of dispersion so that large no
of item get selected and it is less in 3 sigma

Answer / arul

1) Sigma means the standard deviation of the data obtained.
Eg: Turning a shaft for 50mm will never give 50.0000000mm.
There will be variation in the machined dimension. For
measuring the variations v use the parameter standars
deviation. RMS (root mean square) of the deviations from
the mean vaue is standard devation.
2) All the manufacturing & m/c dimensions can be
approximated to lie in a normal curve (bell shaped curve
symm about mean and showing max. freq at mean.)
3) Kindly refer to standard normal curve and its values.

from this ssigma will contined this have many new orbitals
and space contined it was depending upon the 3-sigma was
consisting of them to a sigma
3-sigma was depending on the onther orbetal was determing
the sigma was to be consisting of them to a3-sigma wad
depending on them to consisting on 3-sigma on them to be

My vendor filled liquid oxygen in our 11000 liter capacity tank. He filled from 1400 MMWC up to 3200 MMWC. I followed the provided conversion table and found that we had been supplied 1800 MMWC liquid which is going to yield 2815 cubic meter. On the other hand, the vendor claims that he supplied as follows:- 5236 cub mtr(3200 MMWC)-2124 cub mtr(1400MMWC) = 3112 cub mtr. I fear that he wants to charge 297 cubic meters extra. He claims that my method was wrong and his was right. He says that this disparity is because of the conical shape of the base of the flask. I will be thankful if somebody can explain me the truth.
