Find the area of the shaded region, the graph to the right to pics IQ scores of adults in those scores are normally distributed with a mean of 100 and a standard deviation of 15.

The image displays a bell curve, or normal distribution graph, which is shaded between the values 70 and 115 on the x-axis. The bell curve represents a probability distribution, and the shaded area typically indicates the range or interval that is considered standard or normal for a particular data set. This shaded region likely represents an area where most of the data points fall within one standard deviation from the mean when dealing with a normal distribution, but the exact significance can vary based on the context. The graph also includes zoom and export icons on the right side, suggesting it may be part of an interactive or editable interface.

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.
