u hypergeoPDf [Action][Distribution/Inv.Dist][Discrete][hypergeoPDf]
Function: Returns the probability in a hypergeometric distribution that the success will occur on a specified
trial.
Syntax: hypergeoPDf(
x , n , M , N [ ) ]
Calculation Result Output:
prob
Example: Determine the hypergeometric probability when x = 1, n = 5,
M = 10, N = 20.
u hypergeoCDf [Action][Distribution/Inv.Dist][Discrete][hypergeoCDf]
Function: Returns the cumulative probability in a hypergeometric distribution that the success will occur
between specified lower value and upper value.
Syntax: hypergeoCDf(lower value, upper value,
n , M , N [ ) ]
Calculation Result Output:
prob
Example: Determine the hypergeometric cumulative distribution when lower
value = 0, upper value = 1, n = 5, M = 10, N = 20.
u invHypergeoCDf [Action][Distribution/Inv.Dist][Inverse][invHypergeoCDf]
Function: Returns the minimum number of trials of a hypergeometric cumulative distribution for specified
values.
Syntax: invHypergeoCDf(
prob , n , M , N [ ) ]
Calculation Result Output:
x Inv, ½ x Inv
Important!
See “Important!” under “invBinomialCDf” on page 88.
Example: To determine the minimum number of trials when prob = 0.3, n = 5,
M = 10, N = 20
Using the Financial Submenu
The [Financial] submenu contains commands that are related to financial calculations.
For information about the functions included in this submenu, see “11-4 Financial Calculation Functions”.
Using the Command Submenu
u Define
Function 1: Defines function and registers it with Graph Editor.
Syntax 1: Define{
y1(x) − y100(x) ; x1(y) − x100(y) ; yt1(t) − yt100(t) ; xt1(t) − xt100(t) ;
r1() − r100()} = <expression>
Example: To define the function
y = sin(x) and assign it to line “y3” of the
Graph Editor
Function 2: Creates a user-defined function.
For more information, see “12-3 User-defined Functions”.
u DispStat
Function: Displays previous statistical calculation results.
For more information, see “DispStat” on page 209 and the examples 1208 through 1210 under “Including
Statistical Graphing and Calculation Functions in a Program” on page 225.
