Quizplus · Accepted Answer

The area under the standard normal curve between any two z-scores is always positive, reflecting the probability of observations falling within that range. The area to the left of any z-score is less than 1 because the total area under the curve equals 1, and any point to the left excludes some portion of the curve.
