2. Let X₁,..., X₁ be independent and uniformly distributed on the interval [0, 1]. (a) Write down the pdf for Yi, the ith order statistic. Show that Y; has a Beta distribution. What are its parameters? (b) Find the expected value and the variance of Y₁. (c) Use the previous item to calculate the expected value of Y - Y₁-1, the difference between two successive order statistics. Can you interpret your result?
