**Transcription:**

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.

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

**Graph Explanation:**

The graph on the right is a normal distribution curve, which represents the distribution of IQ scores. The curve is bell-shaped, indicating that it is a normal distribution. The shaded region is to the left of the vertical line at the IQ score of 88. This shaded region represents the proportion of IQ scores that fall below 88. The entire distribution curve centers around a mean IQ score of 100, with a standard deviation of 15. The area of the shaded region corresponds to the cumulative probability of scores below 88.
