The empirical rule states that approximately 68% of all scores lie within one standard deviation of the mean, approximately 95% of all scores lie within two standard deviations of the mean, and approximately 99.7% of all scores lie within three standard deviations of the mean. This means that choices A, B, and C are all consistent with the empirical rule, so the correct answer is D (all of the above).
