This Concept introduces students to the standard normal probability distribution.
Explains how the normal distribution relates to standard deviation and z-scores.
Walks through the steps to solve problems involving the normal distribution with use of the empirical rule and z-scores.
Explains how to tell which real world example would follow a normal distribution.
Explains how to find a z-score for a given data point when you know the mean and standard deviation of the entire normal distribution.
Adjusts the empirical rule to determine the area to left or right of certain points on the normal distribution curve.
