You'll understand where i'm coming from with it.

We have three "identical" punches in the shop working side by side.

Over a 2 week period , punch 1 has snapped 130 widgets.
Punch 2 has snapped 90 widgets.
Punch 3 has snapped 65 widgets.
How should i work this through using Minitab to show that there is significant difference in the three.And when fixed fow to show significant improvement
Thanks all
John
