**Problem Statement:**
Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.
---
**Explanation of Diagram:**
The provided diagram is a normal distribution curve representing IQ scores. It is symmetrical around the mean, which is 100 in this context. The standard deviation is 15, indicating the spread of the scores.
- **Shaded Region:** The shaded part beneath the curve represents the scores between 104 and 130. This area corresponds to the probability or proportion of individuals whose IQ scores fall within this range.
- **Axis and Labels:** The horizontal axis marks the IQ scores. The vertical axis represents the probability density.
---
**Calculation Section:**
To find the area of the shaded region, use the properties of the normal distribution. Round your answer to four decimal places as needed.
The area of the shaded region is: [Box for input]
