12: Once more for luck

And how does Fish-2-Whale compare to MKart? See if you can do all the steps on your own, just using the sample sizes, means, and SD.

  n average SD
MKart Brand   6 192g 15g
Fish-2-Whale   6 26g 44g

You should have found that the difference between treatments was 75g, and that the SEDM was about  19g, so tcalc = 3.9  compared to the tcrit =2.6 for df=5. Now think what does that all mean?
