Casio fx-100AU PLUS - Logical and Negation Operations

Example 3. Specify Fix 3 for the result. (Perform the following operation
after completing the operations in Example 3.)

Important!
• Regression coefficient, correlation coefficient, and estimated value calculations can
take considerable time when there are a large number of data items.
Performing Normal Distribution Calculations
While single-variable statistical calculation is selected, you can perform
normal distribution calculation using the functions shown below from the
menu that appears when you perform the following key operation:
(STAT) (Distr).
P, Q, R: These functions take the argument t and determine a probability
of standard normal distribution as illustrated below.
t: This function is preceded by the argument X, and determines the
normalized variate X
t =
X - x
σx
.
Example 5: For the single variable data {x
n
; freq
n
} = {0;1, 1;2, 2;1, 3;2, 4;2,
5;2, 6;3, 7;4, 9;2, 10;1}, to determine the normalized variate (
t) when x =
3, and P(t) at that point up to three decimal places (Fix 3).
