Hypergeometric distribution (page 6-49)After setting all the parameters, use A to move the highlighting to “Execute” and then pressone of the function keys shown below to perform the calculation or draw the graph.• (CALC) ... Performs the calculation.• (DRAW) ... Draws the graph.I Common Distribution Functions• 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, 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 (G-SLV) (P-CAL) to display the x valueinput dialog box.2. Input the value you want for x and then press U.• 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 T 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 ) to clear the coordinate values and the pointer from thedisplay.• Executing an analysis function automatically stores the x and p values in alpha variables Xand P, respectively.I Normal Distribution• Normal Probability Density (DIST)(NORM)(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.
