The numeric variables in the survey, Age, Mileage, and Odometer, can take any values over a continuous interval and these are examples of continuous RVs. In the previous section we dealt with RVs which had discrete output. In this section we will deal with RVs which have continuous output. A distinction from the previous section needs to be pointed explicitly. In the case of a discrete RV, there is a positive number for the probability of an RV taking on a certain value which is determined by the pmf. In the continuous case, an RV necessarily assumes any specific value with zero probability. These technical issues will not be discussed in this book. In the discrete case, the probabilities of certain values are specified ...
