Answer: your IQ test score is 117
Explanation:
Assume that the mean of a normal distribution of IQ scores is 102 and the standard deviation is 15.
If you have been told that your test score is 1 standard deviation above the mean, it means that your score would be
102 + 15 = 117
According to the empirical rule, 68% of data falls within the first standard deviation from the mean. This means that 117 falls within 68% of the scores.
