Empirical rule

Empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean,  95% are within two standard deviation from the mean,  99.7% are within three standard deviation from the mean.

68% = mean ± standard deviation = 19 ± 7 = (12, 26)

68.0​% of the data will lie between 12 and 26
