![**Probability and Statistics: Normal Distribution**
*Problem Statement:*
Assume the random variable \( x \) is normally distributed with a mean \( \mu = 176 \) and a standard deviation \( \sigma = 20 \). Find the indicated probability.
\[ P(131 < x < 180) \]
---
**Solution:**
To find the probability \( P(131 < x < 180) \), calculate the area under the normal curve between \( x = 131 \) and \( x = 180 \). Use standard normal distribution tables or software for precise calculations.
*Answer Box:*
\[ P(131 < x < 180) = \]
(Round to four decimal places as needed.)
