u Normal Distribution Probability
Normal distribution probability calculates the probability of normal distribution data falling between two specific values.

Data is specified using parameter specification. The following shows the meaning of each item.
| Lower .......................... | lower boundary | 
| Upper .......................... | upper boundary | 
| σ .................................. | standard deviation (σ > 0) | 
| ∝ .................................. | mean | 
| Save Res .................... | list for storage of calculation results (None or List 1 to 26) | 
| Execute ....................... | executes a calculation | 
After setting all the parameters, use c to move the highlighting to “Execute” and then press the function key shown below to perform the calculation.
• 1(CALC) ... Performs the calculation.
