Density Curves, Empirical Rule & Normality, Z-score Intro

I define density curves. I also define Normality through the Empirical Rule. We then introduce the Z-score formula, which is a linear transformation, and show how is allows us to use the Standard Normal Distribution to find p-values. DENSITY CURVES 0:04 EMPERICAL RULE 3:48 Z-SCORE INTRO 6:50 EXAMPLE 11:01 I have no idea what happened to the end of my lesson.  If you need help finding area under a bell curve you can check out    • z-score Calculations & Percentiles in a No...   Thank you very much Summer Rae Newhouse for providing the Closed Captions for this lesson.
