Final answer:
The IQ scores of every person living in the United States would result in a normal distribution, also known as a bell curve.
Step-by-step explanation:
The answer to the question is B) A normal distribution.
A normal distribution, also known as a bell curve, is commonly used to represent IQ scores. In a normal distribution, the majority of the scores cluster around the mean (average), creating a symmetrical and bell-shaped curve. This means that most people fall within the average range, with fewer people having scores that are significantly higher or lower.
For example, if we were to plot the IQ scores of every person in the United States on a graph, we would expect to see a normal distribution, with the majority of scores around the national average IQ.
