Explanation:

Step1: Properties of normal distribution

In a normal distribution of IQ scores, the mean, median, and mode are equal. The mean of IQ scores is 100. The most common score (mode) is the mean.

Step2: Center of the distribution

The center of a normal distribution is at the mean. Since the mean of IQ scores is 100, a score of 100 is at the center.

He would have scored 100, which would have been in the center of the distribution.
