8 0 Fig. 1 for Question An amateur statistics practitioner proudly shows you the graph above (Fig. 1) and insists that it is a proper probability distribution function (PDF) for a continuous random variable X. He is positive that the area of the parallelogram should be adequate for a PDF. a) Determine the value of K so that the graph is a probability distribution. b) Define f(X) for the graph such that the area under the curve properly shows the probability density of X from 0 to 10. Hint: you may have to revise the graph so that a proper Algebraic function can be defined, but still reflect the area of the polygon as probability c) Give the standard deviation of X. Show your solution in good form. d) Determine the median and mode of X.
