Common Distribution Functions; Normal Distribution - Casio fx-9750GII User Manual

• (DIST)
After setting all the parameters, use
one of the function keys shown below to perform the calculation or draw the graph.
• (CALC) ... Performs the calculation.
• (DRAW) ... Draws the graph.

Common Distribution Functions

• V-Window settings for graph drawing are set automatically when the Setup screen's "Stat
Wind" setting is "Auto". Current V-Window settings are used for graph drawing when the "Stat
Wind" setting is "Manual".
• After drawing a graph, you can use the P-CAL function to calculate an estimated
x
a particular value. The P-CAL function can be used only after a Normal Probability Density,
t
Student- Probability Density,
The following is the general procedure for using the P-CAL function.
1. After drawing a distribution graph, press
input dialog box.
2. Input the value you want for
• This causes the
pointer to the corresponding point on the graph.
3. Pressing or a number key at this time causes the
so you can perform another estimated value calculation if you want.
4. After you are finished, press
display.
• Executing an analysis function automatically stores the
and P, respectively.
