STAT 1100 Chapter Notes - Chapter 6: Linear Map, Unimodality, Cumulative Distribution Function
Document Summary
This is a unimodal distribution, which it has a single peak point where df dx. It is a symmetric distribution, which means that f (x) = f ( x). We say that functions with this property are even func- tions. Limit values: x + f (x) = 0. x f (x) = lim lim x f (x) = 0 lim lim x + f (x) = 1. The standard normal distribution is a regular normal dis- tribution with parameters. Our goal is to move on to some business situations where the random variable of interest is continuous. Consider for example the time that a person takes on buy- ing groceries at the store, or the cycle time for a widget on a product line. Think also on a logistics company determin- ing how to best load their freighters. The weight of each box can be considered also a continuous random variable.
