Upper Lower Spec Limits transformation by Johnson Fit

After tranforming data from non normal distribution by johnson fit , and getting a distribution that is now normal distributed , can the new limits be also shown ?

 

for example in this test , the original limits were 0 and 10 , what are the new limits in the transformed data by Johnson fit ?

Hi @carloaz : Generally speaking, whatever formulae you used to transform the data (to Normal) should be used to transform the specs.
