Using z-score table in Normal Distribution Problems

Tables found at: https://en.wikibooks.org/wiki/....Engineering_Tables/N

Z-scores are used to relate any normal distribution to the standard normal distribution (mean =0, standard deviation =1). Once you have a z-score, you have to use a z-score table in order to calculate probabilities or areas underneath the standard normal curve.

This video focuses on how to use a z-score table to answer simple questions about z-scores and the percent of the distribution contained below, above, or between given z-scores.
