If the spec limits on an important quality characteristic are 2.75 standard deviations below and above the mean value of this characteristic, what is the estimated process fallout? If needed, see a standard normal distribution function table.
If the spec limits on an important quality characteristic are 2.75 standard deviations below and above the mean value of this characteristic, what is the estimated process fallout? If needed, see a standard normal distribution function table.
Solution
Z value here = 2.75
From the standard normal distribution table,
p=0.00298
Required probablity =2p = 0.00596
=0.596%
