A z-score of 1.96 and -1.96 represents approximately the 97.5th and 2.5th percentiles, respectively, of a standard normal distribution. Therefore, if a vertical line is drawn at either of these z-scores, it would capture 47.5% of the distribution on one side (between the line and the mean) and 47.5% on the other side (between the line and the other end of the distribution).
