5.......... 9...........5
6.......... 7...........5
-----------------------------
Ho: p1=p2=...=p6
Ha: at least one of the proportions is different
------------------
Run a Chi-Sq Test to get:
Test statistic: Chi-Sq = 3.8528...
p-value: 0.5707
Conclusion: Fail to Reject Ho.
The test supports the conclusion that the die is not biased.
