Quizplus · Accepted Answer

A score of 130 in a standard score system with a mean (M) of 100 and a standard deviation (SD) of 15 is 2 standard deviations above the mean. In a normal distribution, this corresponds to the 97.5th percentile. However, since the question asks for the closest answer, 98 (C) is the correct choice, as it is the closest to the actual percentile value.
