Definition of Terms
x : data valu�e
σ: population stan�dard deviation (σ > 0) μ : population m�ean
Specifying σ = 1 and μ = 0 produces standard normal distribution.
Calculation Result Output
prob : normal probabilit�y density
Example
Data : 37.5
Population stan�dard deviation : 2
Population m�ean : 35
