Can anyone tell me how to get JMP to give a very simply variance component
analysis?

I'm trying to quantify lot-to-lot variability of a raw material.  I've made
two independent measurements of 9 lots.  I'd like to segregate the overall
variance into within lot variation (coming from run-to-run variation) and
between lot (lot-to-lot) variation.  I'd like the total variance to be
reported as the two components.
   Attached is the example data set.
 <<Example Data.JMP>> 
   It seems like this should be very simple but I can't seem to get the
answer without doing the calculations by hand.
Thanks,
Sean
