![Suppose that \( \chi^2 \) follows a chi-square distribution with 20 degrees of freedom. Use the ALEKS calculator to answer the following.
---
(a) Compute \( P(12 \leq \chi^2 \leq 31) \). Round your answer to at least three decimal places.
\[ P(12 \leq \chi^2 \leq 31) = \boxed{\ } \]
(b) Find \( k \) such that \( P(\chi^2 \geq k) = 0.1 \). Round your answer to at least two decimal places.
