Normal probability density
Normal probability density calculates the probability that data taken from a normal
distribution is less than a specific value. Normal probability density is applied to
standard normal distribution.

Data is specified using parameter specification. The following shows the meaning
of each item.

..................... data
%
..................... population standard deviation (

µ
..................... population mean
Execute .......... executes a calculation or draws a graph
• Specifying
%

µ
= 0 specifies standard normal distribution.
Example
To calculate the normal probability density for a specific
parameter value
For this example, we will calculate the normal probability
density when
x
= 36,
%
= 2 and
µ
= 35.
