Question

What is the probability that an individual, selected at random, will score below the mean on any normally distributed characteristic?

Answer 1

Answer:

the probability that an individual, selected at random, will score below the mean on any normally distributed characteristic is just about 0.5.

Step-by-step explanation:

This probability in normal distribution corresponds to z-score of 0. Using normal distribution tables.

P(z < 0) = 1 - P(z ≥ 0) = 1 - 0.5 = 0.5

Which is very logical, to score below the mean on a normal distribution, the probability is just less than 0.5.
