If in the population, intelligence is normally distributed, it means that:

Correct option is B

If intelligence is normally distributed in the population, it means that most people fall around the average level of intelligence, with fewer individuals at the extremes of very high or very low intelligence.
Information Booster:
1. Normal Distribution: A bell-shaped curve where most observations cluster around the mean.
2. Mean (Average): The central value of a data set.
3. Standard Deviation: A measure of the dispersion of data points around the mean.
4. IQ Scores: Intelligence quotient scores typically follow a normal distribution.
5. Percentiles: Indicate the relative standing of a score within a distribution.
6. 68-95-99.7 Rule: In a normal distribution, about 68% of data falls within one standard deviation of the mean, 95% within two, and 99.7% within three.
Additional Information:
· Everyone has approximately the same level of intelligence (a): Incorrect interpretation of normal distribution.
· Most people are average in terms of intelligence (b): Correct interpretation; majority are near the mean.
· Most people have extremely high intelligence (c): Incorrect; few are at the extremes.
· Most people have extremely low intelligence (d): Incorrect; few are at the extremes.
