- prove the density function is a sufficient statisticTwo high school seniors find themselves with much time and nothing to do. They decide to devise a computer game in which a cursor moves randomly along the x axis between –2 and 2. The game they play is to stop the cursor at random points between –2 and 2 without looking at the screen. Such a game results in a uniform distribution over the interval between –2 and 2 and resembles a density curve. the height of a density curve isLet the radius of a circle be a random variable X with density function f(x) = 1 for 0 < x < 1 and f(x) = 0 otherwise. What is the probability density of the area of the circle?
