Answer: The corresponding z-score would be - 0.085 for a cumulative area of 0.4661.

When you look on a normal distribution table, you will see that the value of 0.4661 falls between z-scores of - 0.08 and - 0.09. Therefore, we should find the middle of those 2 numbers to get the best possible approximation. That would be - 0.085 for the z-score.
