Is the process of converting an x value from a normal distribution into a z score (units oflength sigma from the center mu)
Z score formula
Z score reports how many an x value lies from the mean and in which direction.
Applet results
1.Decreasing mu increasing area to left of z
2.Increase x increase in area to left of z score
3.sigma increase widens the graph
Comparing Areas of Normal vs Std.Normal Curve
1. Area to right of z score=Area to right of x value
2.Area to left of z score=Area to left of x value
Find Area Process
1.Given x--Standardize--Use Std.Norm Table--Area
2.Given Area--Use std.norm table--find z--convert to x
