Data is specified using parameter specification. The following shows the meaning
of each item.
Lower ............. lower boundary
Upper ............. upper boundary
df
.................... degrees of freedom (positive integer)
Execute .......... executes a calculation
Example
To calculate
χ
2
distribution probability for a specific parameter
value
For this example, we will calculate
χ
