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

The image presents a standard normal distribution curve, also known as a bell curve. This symmetric curve represents a normal distribution with mean zero and standard deviation one.

The shaded area under the curve on the left side of the vertical line represents the probability of a Z value being less than -1.03. The vertical line intersects the horizontal axis at z = -1.03. This Z value indicates how many standard deviations an element is from the mean.

Understanding and calculating the area under the curve for certain ranges of Z values is crucial in statistics, as it helps determine probabilities and make inferences about a population based on sample data.

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.
