Question

Quizplus · Accepted Answer

In a standard normal distribution, 2% of scores falling between z-scores typically indicates a small area under the curve, often in the tails. The correct choice is C (2; 3) because it represents a narrow range in the upper tail of the distribution, where a small percentage of scores would be found. Choices A and B cover too broad a range, encompassing much more than 2% of the distribution, and D extends beyond the typical range used for most z-score calculations.
