Green Valley Ranch using unbalanced dice ...

Green Valley Ranch Casino near Las Vegas seems to be using unbalanced dice based upon roll data collected there in July, 2013:

467 Rolls broken down as follows
2's = 15
3's = 33
4's = 55
5's = 44
6's = 60
8's = 67
9's = 33
10's = 41
11's = 24
12's = 22

The 7's broke down like this:
6/1 = 40
5/2 = 20
4/3 = 13 


The Chi^2 test on those rolls is in the warning range. p = 0.000092, including the 7 splits provided.

The data suggests that sample was not collected from fair dice.
