Question

When applicable,the empirical rule provides the approximate percentage of observations that fall within how many standard deviations from the mean? A)1,2,or 3 standard deviations B)2,3,or 4 standard deviations C)k standard deviations for every k > 1 D)1 - 1/k² standard deviations for every k > 1

Quizplus · Accepted Answer

The empirical rule states that for a normal distribution, approximately 68% of the observations fall within one standard deviation of the mean, approximately 95% within two standard deviations, and approximately 99.7% within three standard deviations.
