Final answer:

The best description of a normal distribution includes symmetry around the mean, equal mean, median, and mode, and an area under the curve equal to 1.0.


Explanation:

The best description of a normal distribution is:

  1. Normal distributions are symmetric around their mean.
  2. The mean, median, and mode of a normal distribution are equal.
  3. The area under the normal curve is equal to 1.0.
  4. Normal distributions are denser in the center and less dense in the tails.

In the context of distributions for averages, being symmetrical around the mean and having an area under the curve of 1 are key aspects of a normal distribution.
