Do you agree that "The odds of a failure within a six sigma process are 3.4 in a million"? Explain
In six sigma, process is allowed to move with 1.5sigma along with the both sides of means.
So, from the left side of the curve we have (6sigma-1.5sigma)= 4.5sigma
And, from the right side of the sigma we have (-6sigma-1.5sigma)= -7.5sigma
With this rejection rate would be 3.4 million defects per million opportunities.
For the mathematical reason please look into the attachment graph i have drawn using R program.
So, yes i agree with the statement.
