• 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 p-value for a particular x value. The P-CAL function can be used only after a Normal Probability Density, Student-t Probability Density, Ƶ2 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 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 variables X and P, respectively. k Normal Distribution • Normal Probability Density Normal Probability Density calculates the probability density (p) for a specified single x-value or a list. When a list is specified, calculation results for each list element are displayed in list form. 5(DIST)1(NORM)1(Npd) • Normal probability density is applied to standard normal distribution. • Specifying Ʊ = 1 and ƫ = 0 specifies standard normal distribution. Calculation Result Output Examples When 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 as data. 6-51
