The shaded area in the following graph indicates the area to the left of x. This area is represented by the probability P (X < x). Normal tables, computers, and calculators provide or calculate the probability P (X <x).

Shaded area

represents probability

The area to the right is then P(X>x) = 1- P(X < x). Remember, P(X<x)= Area to the left of the vertical linAsk through x. P(X<x)=1-P(X<x) =

Introductory Statistics follows scope and sequence requirements of a one-semester introduction to statistics course and is geared toward students majoring in fields other than math or engineering. The text assumes some knowledge of intermediate algebra and focuses on statistics application over theory.
