In the Math menu, PI does not perform calculations; it enters PI for calculations. You may start an operation, use the Math menu to execute a function, and continue calculating with your original operation without losing your work.

The Probability Sub-menu

Lower Tail Normal Distribution (LTND) calculates the probability for a normally distributed, random variable to be less than the input.

Inverse Lower Tail Normal Distribution (LTND-1) is the inverse function for LTND; it calculates the value (V) for which the probability of a normally distributed, random variable to be less

than V is the given input. Student, Inverse Student, Chi2 (χ 2), Inverse Chi2, F-Distribution and Inverse F-Distribution perform similar operations for Student, Chi2, and F-Distributions.

Student, Chi2, and F-Distribution and their inverse operations are special cases, as they

require more than one number as input. Student and Chi2 require (N), the number of degrees of freedom, and F-Distribution requires (N1) and (N2), two degrees of freedom.

To perform Student and Chi2 operations or their inverse:

1.Enter the number of degree(s) of freedom by typing the number and pressing I or =.

2.Type the number for which you want to calculate the probability, or, for the inverse, the probability for which you want the number.

3.Navigate to the appropriate function in the Probability sub-menu of the Math menu.

To perform F-Distribution operations or their inverse:
