Unit 5 deals with two types of discrete random variables, theBinomial and the Poisson, and two types of continuous randomvariables, the Uniform and the Exponential. Depending on thecontext, these types of random variables may serve as theoreticalmodels of the uncertainty associated with the outcome of ameasurement.
Give an example, USING YOUR OWN WORDS (NOT TEXT COPIED FROMTHE INTERNET), of how either the Poisson or the Exponentialdistribution could be used to model something in real life (onlyone example is necessary). You can give an example in an area thatinterests you (a list of ideas is below). Give a very roughdescription of the sample space.
If you use an idea from another source, please provide acitation in the sentence and a reference entry at the end of yourpost. Include a citation even if you paraphrase from a website.Please do not copy blocks of text from the Internet--try to useyour own words.
When forming your answer to this question you may give anexample of a situation from your own field of interest for which arandom variable, possibly from one of the types that are presentedin this unit, can serve as a model. Discuss the importance (or lackthereof) of having a theoretical model for the situation. Peoplecan use models to predict business conditions, network trafficlevels, sales, number of customers per day, rainfall, temperature,crime rates, or other such things.
