![**Finding Critical Chi-Square Values**
For a given level of confidence and sample size, it's crucial to determine the critical values of chi-square (χ²) for both the upper (χ²ᵁ) and lower (χ²ᴸ) bounds. These values are essential in statistical analysis, especially in hypothesis testing.
### Instructions:
- **Use three decimal places for accuracy.**
- **Hint:** If your answers seem incorrect, try switching them.
### Exercises:
#### a) For 90% confidence, with a sample size \( n = 20 \):
- **Upper Critical Value (χ²ᵁ):** [Enter value]
- **Lower Critical Value (χ²ᴸ):** [Enter value]
#### b) For 99% confidence, with a sample size \( n = 14 \):
- **Upper Critical Value (χ²ᵁ):** [Enter value]
- **Lower Critical Value (χ²ᴸ):** 3.5 (Incorrect)
#### c) For 95% confidence, with a sample size \( n = 25 \):
- **Upper Critical Value (χ²ᵁ):** 29 (Incorrect)
- **Lower Critical Value (χ²ᴸ):** 29 (Incorrect)
The provided answers in some cases are incorrect, as indicated by the red "X." Double-check calculations and ensure all values correctly correspond to the respective chi-square distribution tables.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5f23cef6-8168-49e8-a2d7-23f21c519658%2F759e36e5-ef7d-4f81-8fff-723497ce39a6%2F64oq2hd_processed.jpeg&w=3840&q=75)
