The critical value is wrong.

Conduct the hypothesis test and provide the test statistic and the critical value, and
state the conclusion.
A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it
200 times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6,
respectively: 25, 31, 47, 42, 26, 29. Use a 0.10 significance level to test the claim that
the outcomes are not equally likely. Does it appear that the loaded die behaves
differently than a fair die?

The test statistic is 12.280.
(Round to three decimal places as needed.)
The critical value is 0.031
(Round to three decimal places as needed.)
