### Problem Statement:

**Find the area of the shaded region.** The graph to the right depicts IQ scores of adults, and these scores are normally distributed with a mean of 100 and a standard deviation of 15.

- [Click to view page 1 of the table.](#)
- [Click to view page 2 of the table.](#)

**Instructions:**

The area of the shaded region is [_____] (Round to four decimal places as needed.)

### Diagram Explanation:

The graph shown is a normal distribution curve illustrating IQ scores. The mean IQ score is marked at 100, and the standard deviation is 15. The shaded region to the left of the curve indicates a specific segment of the distribution. A vertical line is drawn down from the curve at 70, suggesting this might be the boundary of the shaded region. This area under the normal curve needs to be calculated.

### Additional Features:

An interactive answer box is provided for input. After entering the answer, you can select "Check Answer" to verify the response.

---

This walkthrough helps in understanding how to calculate the area under a normal distribution curve using standard deviations, important for statistical analysis and educational purposes.
