Quizplus · Accepted Answer

In a normal distribution, approximately 68% of the scores fall within one standard deviation above and below the mean, leaving 32% of scores outside of that range. Since the distribution is symmetrical, half of the 32% is above one standard deviation above the mean, which is roughly 16%. Therefore, the answer is B.
