The number of degrees of freedom is (n－1)＝5. Consult statistical tables to find χ2 to a significance level of 0.05 with 5 degrees of freedom. The table shows that χ02.05,5 ＝11.07. Since the computed value (5.00) is less than 11.07, you can conclude that, to a 0.05 significance level (95% probability), the die is fair.
