Question 80:



No answer provided yet.From what I see, you'd need to add up all the brackets that are outside the tolerance limit, so anything above +30 degrees. If you found 1 out of 100 for example, your percentage out of tolerance would be 1% or 99% in tolerance. You could then convert this to a process-sigma by using Percentile to Z calculator and enter .99 (99 percent) and 1 sided (since you only have a 1 sided tolerance level). This provides a z-score of 2.33. If you include the 1.5 σ shift in your Process Sigma you would then add 1.5 to this, providing you with a Process Sigma of 3.83.
