Step 1
Empirical rule :
According to empirical rule ,
1)68% of data falls within the first standard deviation from the mean
In mathematical notation, this is represented as: μ ± 1σ
2) 95% fall within two standard deviations
In mathematical notation, this is represented as: μ ± 2σ
3)99.7% fall within three standard deviations.
In mathematical notation, this is represented as: μ ± 3σ
