    Suppose a normal QQ-plot is drawn using a reasonably large sample x1,x2,…xn from an unknown probability distribution. For which of the following distribution would you expect the QQ-plot to be convex (J-shaped)?

    1. Beta(5,1)
    2. Exponential(1)
    3. Uniform(0,1)
    4. Geometric(1/2)

    The following facts would help to guess the answer:
