    In the six sigma product report of Minitab. If i entered the defects 999999 and total units as1000000 and opportunities as 1. I am getting the Z bench mark as 1.5. But i did calculation in Excel using the formula i am getting value as -3.268.  Why minitab is showing 1.5 as z bench mark instead of -3.268. Please send your explanations to this mail id as soon as possiblee.

    Check your output.  I think you may be looking at the Zshift column.  If you don’t put in a shift factor Minitab automatically uses the 1.5 here.  I ran the same data and I get a Zbench of -3 with a Zshift of 1.5.

    I also plugged the same data and got a Zbench of 1.5. For your info I am using Minitab release 12.2

    Check your version of the Six Sigma Academy module.  You should have version 2.12.  You can check this under SixSigma->About MINITAB Six Sigma Academy module.  I think the calculations were changed from 2.11 to 2.12.

    I was wondering if you were ever going to respond to one of these things.
    On a scale of 1 to 10 to information garnered from that module is worth?
