Transcribed Image Text:Areas under the Standard Normal Curve
The column under A gives the fraction of
the area under the entire curve that is
between z= 0 and a positive value of z
A
0
2
Because the curve is symmetric about the
0-value, the area between z= 0 and a
negative value of zcan be found by using
the corresponding positive value of z.
