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?

**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?

### Statistical Analysis Example

**The test statistic is** [ ]. *(Round to three decimal places as needed.)*

**The critical value is** [ ]. *(Round to three decimal places as needed.)*

**The P-value is** [ ]. *(Round to four decimal places as needed.)*

### State the Conclusion

\[ \square \] \(H_0\). There \[ \triangle \] sufficient evidence to support the claim that the outcomes are not equally likely. The outcomes \[ \diamond \] to be equally likely, so the loaded die \[ \pentagon \] to behave differently from a fair die.

### Instructions:
1. **Test Statistic**: Input the calculated test statistic value and round it to three decimal places.
2. **Critical Value**: Enter the critical value for the test, also rounded to three decimal places.
3. **P-Value**: Provide the P-value calculated from the test and round it to four decimal places.

### Conclusion Options:
- Choose whether to reject or fail to reject \(H_0\).
- State whether there is sufficient or insufficient evidence.
- Indicate whether the outcomes seem or do not seem to be equally likely.
- Decide whether the loaded die appears or does not appear to behave differently from a fair die.

This framework aids in conducting hypothesis tests to draw conclusions about statistical data distributions and their fairness.
