This statistics video tutorial provides a basic introduction into standard normal distributions. It explains how to find the Z-score given a value of x as well as the mean and standard deviation. It explains how to determine the probability by finding the area under the curve represented by f(x) - the probability density function using the empirical rule and the Z-tables. This video contains plenty of examples and practice problems.
Here is a list of topics:
0:00 - Introduction into standard normal distributions
6:55 - How To Find The Z-scores Given x
8:37 - How To Calculate x Given The Z Score
10:33 - Calculating Probability Using The Empirical Rule
