Continuous Probability Distributions Examples. For example you can calculate the probability that a man weighs between 160 and 170 pounds. Because there are infinite values that X could assume the probability of X taking on any one specific value is zero. Probability Distributions for Continuous Variables Suppose the variable X of interest is the depth of a lake at randomly chosen point on the surface. Given the probability function P x for a random variable X the probability that X belongs to A where A is some interval is calculated by integrating p x over the set A ie Where 0.
What are the height and base values. Examples of continuous data include. The normal and standard normal. Given the probability function P x for a random variable X the probability that X belongs to A where A is some interval is calculated by integrating p x over the set A ie Where 0. Examples of continuous probability distributions. 0 otherwise a calculate the mean and variance of X.
To calculate the chance of an interval we required integrals.
Note that here it does not matter if we use or as each individual point has probability zero so for example P X 2 P X 2. Some Special Continuous Distributions Example. Show the total area under the curve is 1. We state the convolution formula in the continuous case as well as discussing the thought process. So for example if a b R with a b and X has a continuous distribution on the interval a b then we could also say that X has a continuous distribution on a b or a b or a b. Figure 41 shows the CDF of X.
