Document Summary
Introduction to probability models: paul the octopus. A coin is tossed 10 times, and a student is asked to guess the outcome of the coin toss. Let us assume, for the time being, that there is no esp. Y = random variable with 11 possible values. We can construct the probability distribution of y. Plan: select 25 students from the class, and have each person carry on the experiment. Record the variate yi for each i=1,2, 25. Data: y1, y2, y3, y25, and compute the average. Where each yi has the same probability function and y1, y2, y25 are independent. Y = (y1 +y2 + y25)/25, so that, if the. Let model applies, the observed average y =5. 5 is a realization of. To answer the question, we calculate. Summary: to make a meaningful analysis, we have to know the distribution of y and the distribution of. S (the possible realizations of y), we specify.
