Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1.

The area of the shaded region is

(Round to four decimal places as needed.)

The image illustrates a standard normal distribution curve, also known as a bell curve. It is a symmetrical, Gaussian distribution. In this graph, a vertical line marks a specific z-score, labeled as \( z = -0.94 \).

The region under the curve to the right of this line is shaded in light blue. In the context of a standard normal distribution, the z-score represents the number of standard deviations an element is from the mean. A z-score of \(-0.94\) indicates that the value is 0.94 standard deviations below the mean.

This diagram is typically used to calculate probabilities or to find percentiles in statistics, related to how much of the data falls below this particular z-score.

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.
