Answer

Brief Explanations:

The standard normal distribution is symmetric about z = 0. The area to the left of z = 0 is 0.5. If the area to the left of a z - score is less than 0.5, it means the z - score is to the left of 0 on the standard normal distribution curve, so it must be negative.

Answer:

D. The z - score must be negative.
