6-51• V-Window settings for graph drawing are set automatically when the Setup screen’s “StatWind” setting is “Auto”. Current V-Window settings are used for graph drawing when the “StatWind” setting is “Manual”.• After drawing a graph, you can use the P-CAL function to calculate an estimated p-value fora particular x value. The P-CAL function can be used only after a Normal Probability Density,Student-t Probability Density, 2 Probability Density, or F Probability Density graph is drawn.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 xvalue 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 thepointer 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 reappearso 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 thedisplay.• Executing an analysis function automatically stores the x and p values in variables X and P,respectively.k Normal Distribution• Normal Probability Density 5(DIST)1(NORM)1(Npd)Normal Probability Density calculates the probabilitydensity (p ) for a specified single x-value or a list. When alist is specified, calculation results for each list element aredisplayed in list form.• Normal probability density is applied to standard normal distribution.• Specifying = 1 and = 0 specifies standard normal distribution.Calculation Result Output ExamplesWhen a list is specified Graph when an x-value is specified• Graphing is supported only when a variable is specified and a single x-value is entered asdata.
