Distribution

u Common Distribution Functions

After drawing a graph, you can use the P-CAL function to calculate an estimated p-value for a particular x value.

The following is the general procedure for using the P-CAL function.

1.After drawing a distribution graph, press !5(G-SLV) 1(P-CAL) to display the x value input dialog box.

2.Input the value you want for x and then press w.

•This causes the x and p values to appear at the bottom of the display, and moves the pointer to the corresponding point on the graph.

3.Pressing v or a number key at this time causes the x value input dialog box to reappear 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 x and p values in alpha variables X and P, respectively.
