Normal Distribution - Casio FX-CG10 Software User's Manual

• 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 !5(G-SOLVE) 1(P-CAL) to display the
value input dialog box.
2. Input the value you want for
• This causes the
pointer to the corresponding point on the graph.
3. Pressing v 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 J to clear the coordinate values and the pointer from the
display.
• Executing an analysis function automatically stores the
