k Drawing a Normal Probability Distribution Graph
You can draw a normal probability distribution graph using manual graphing with the
RUN • MAT (or RUN ) mode.
1. From the Main Menu, enter the RUN • MAT (or RUN ) mode.
2. Input the commands to draw a rectangular coordinate graph.
3. Input the probability value.
Example To draw a normal probability P (0.5) graph.
1 m RUN • MAT (or RUN)

k Calculations Using the Distribution Function
Important!
• The following operations cannot be performed on the fx-7400GIII.
You can use special functions in the RUN • MAT mode or PRGM mode to perform calculations
that are the same as the STAT mode distribution function calculation (page 6-40).
Example To calculate normal probability distribution in the RUN • MAT mode for
the data {1, 2, 3}, when the population standard deviation is
σ
= 1.5 and
the population mean is
= 2.
