Hi, Everyone,
I just want some advice regarding a project for reducing destructive samples in crimping process. I started an analises to justify that to our customer
1.- went to CPk calculations last 3 months.. results were above 2.0 CPK value
2.- I tried to make an Hypotheses test to justify reduction of destructive samples (from 40 to 20) to do that I used F fischer test estimating variance between 2 samples.
3.- According to calculations there is not significant difference between varaiances of the 2 samples.. therefore shall I go forward and reduce the sampling with the information..
Help is welcomed
