About ______ of z-scores in the standard normal distribution are between the z-scores ±1.96.

A) one-third
B) half
C) two-thirds
D) 95%

The area under the standard normal distribution between z-scores ±1.96 represents 95% of the total area, which means that 95% of the z-scores in the standard normal distribution lie between these two values. This is a well-known rule commonly used in statistical inference and hypothesis testing.
