The z-score for which the area under the standard normal curve to its left is 0.40 is approximately -0.25. This is because a z-score represents the number of standard deviations a point is from the mean, and an area of 0.40 to the left indicates a value below the mean (which is 0 in a standard normal distribution), hence a negative z-score.
