In a normal distribution, approximately 50% of the z-scores will be negative because the mean (which is the center of the distribution) is assigned a z-score of 0, and approximately half of the scores will fall to the left of the mean. This is because the normal distribution is symmetric, meaning that the shape of the distribution to the left of the mean is a mirror image of the shape to the right of the mean. Therefore, approximately 50% of the z-scores will be negative.
