Once again, other than a little rounding error, the CDF tells us the same thing as the PDF. This time, under Show percentile lines at Y values, enter 95 for 95. For every interval A a b, the number PA Z b a f(x) dx is the probability of the event. Now right-click the CDF and choose Add > Percentile Lines. In probability theory one considers functions too: De nition: A non-negative piece-wise continuous function f(x) which has the property that R 1 1 f(x) dx 1 is called a probability density function. ![]()
