Let X denote the amount of time for which a book on a 2-hour reserve at a college library is checked out by a randomly selected student and suppose the CDF is: F(x) = 0 x² { 1 4 x < 0, 0 ≤ x < 2, 2 ≤ x. Use this to compute the following: (a) P(X ≤ 1), P(0.5 ≤ X ≤ 1), and P(X > 0.50). (b) Find the median checkout duration ? η 0x (c) E(X), V(X) and o (d) P(x ≥ μ + O₂).
