Question
![**Scenario Description:**
Andre recently found a die (the traditional, six-sided variety) at the park. He took it home and rolled it 100 times and recorded the results (found in the table below). Is this a 'fair die' or has it been tampered with? Test at the \(\alpha = 0.10\) level of significance.
**Hypotheses Options:**
1. \(\mathbf{H_0:}\) The die is a fair die; \(\mathbf{H_1:}\) The die has been tampered with.
2. \(\mathbf{H_0: \mu_1 = \mu_2;}\) \(\mathbf{H_1: \mu_1 \neq \mu_2}\)
3. \(\mathbf{H_0: p_1 = p_2;}\) \(\mathbf{H_1: p_1 \neq p_2}\)
4. \(\mathbf{H_0:}\) The die has been tampered with; \(\mathbf{H_1:}\) The die is a fair die.
**Roll Count Table:**
\[
\begin{array}{|c|c|}
\hline
\text{Rolled} & \text{Count} \\
\hline
1 & 1 \\
2 & 8 \\
3 & 5 \\
4 & 3 \\
5 & 3 \\
6 & 80 \\
\hline
\end{array}
\]
**Test Statistic (2 decimals):**
[Input field for the test statistic]
**P-value (4 decimals - if less than 0.001 answer 0):**
[Input field for the P-value]
**Decision on Null Hypothesis:**
- [ ] Reject the Null Hypothesis
- [ ] Do not Reject the Null Hypothesis
**Conclusion:**
- [ ] There is not enough evidence to suggest that the die has been tampered with.
- [ ] There is enough evidence to suggest that the die has been tampered with.
**Diagram Explanation:**
The table outlines the number of times each face of the die appeared out of 100 rolls. The counts are highly skewed, with the number '6' appearing 80 times, suggesting potential tampering if the die was expected to be fair with an equal distribution of outcomes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F24033adb-df78-46b5-9e2c-955a774154aa%2F7fb72673-7789-499a-abda-4ce034c4188a%2F5un16ks_processed.jpeg&w=3840&q=75)
