The image displays a standard normal distribution curve (bell curve) with the x-axis labeled as "z". The curve is centered at 0, indicating the mean of the distribution. A section of the curve is shaded to the left of 0, starting from approximately -2.03 on the z-axis, highlighting the area under the curve in that region. This shaded area represents the probability of a z-score falling between -2.03 and 0 in a standard normal distribution, which is useful for statistical analysis and hypothesis testing. The curve illustrates typical properties of a normal distribution, such as symmetry about the mean and the concentration of most data around the center of the curve, tapering off as it moves further away.
