According to the empirical rule, in a normal distribution, approximately 1 standard deviation of the mean, approximately \( \% \) of the data lie within plus or minus of the mean, and approximately \( \% \) of the data lie within plus or minus 3 standard deviations of the mean. According to the empirical rule, in a normal distribution, approximately \( \% \) of the data lie within plus or minus 1 standard deviation of the mean, approximately \( \quad \% \) of the data lie within plus of minus 2 standard deviations of the mean, and approximately \( \% \) of the data lie within plus or minus 3 standard deviations of the mean.
