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.

Answer / raju.j
This is about amount of rejection of Parts Per Million(PPM)
products...
In 6sigma industry 3.4parts only rejected i.e defected per
million product....99.9997% products are good.
In 3 sigma industry 2700parts are rejected i.e defect per
million product....

Answer / pradeep
6-was containg the orbetal was different was determaining
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
obtained them. .
