1 Section 1.3: The Normal Distribution Learning goals for this chapter: Know when and how to use the empirical (68-95-99.7% rule). Understand what the standard Normal distribution is and how it is related to other Normal distributions. Calculate both forwards and backwards Normal distribution problems. Draw a Normal distribution curve appropriate for a story. Normal curves N( , σ) Bell-shaped, unimodal, symmetric Mean, , always in the center of the curve (the peak) Standard deviation, σ, controls the spread of the graph (wide or narrow) Probabilities are just the area under the curve (integral) between the points of interest Total area under the Normal curve = 1 (or 100%) Curve stretches from - to + , but the area under the curve gets very small the farther you go from the mean. In the last set of Chapter 1 notes, we discussed bell-shaped distributions, standardization, and the 68-95-99.7% rule. Standard Normal Distribution
