4. Write a MATLAB function that draws N i.i.d. random variables X; from a distribution a. fx(x) = x/2 0 < x < 2 The output of your function should be a single number: the average all the N generated random variables W = N Xi Run your code for N=2, N=10, and N=200 and present a printout of your code and the results. b. Loop you code 5,000 times for N=2, N=10, and N=200 and plot histograms of W. When you plot your histograms, specify the x-axis limits to be between 0 and 2.
