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.

a. The area of the shaded region is

(Round to four decimal places as needed.)

The image shows a normal distribution curve, also known as a bell curve. This graph represents a probability distribution that is symmetric about its mean, indicating that data near the mean are more frequent in occurrence than data far from the mean.

### Key Elements of the Graph:

- **Normal Distribution Curve**: This is illustrated as a smooth, symmetric bell curve that depicts the distribution of a dataset.
- **Shaded Area**: The area under the curve is shaded in light blue to signify a specific range of the data. This shaded portion typically represents the probability or percentage of data points that fall below a certain threshold.
- **Vertical Line at 82**: The vertical line at the value 82 on the x-axis marks a cutoff point. This line separates the shaded area from the rest of the distribution, indicating that the shaded region includes all data points up to the value of 82.

The shaded area helps visualize the proportion of the dataset that lies within a specific range, emphasizing the probability of a data point being less than or equal to 82 in this context. This type of graph is commonly used in statistics to represent data in fields such as education, research, and social sciences.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
