Let X denote the amount of time a book on 2-hour reserve in the Killam Library is checked out by a randomly selected Dalhousie student. Suppose X has the density function f(x) = 0.5 x for (0 ≤ X ≤ 2) otherwise f(x) = 0. Compute the following probabilities,
a.) P(X ≤ 1.3) (Give decimal answer to two places past decimal.) Tries 0/2
b.) P(0.8 ≤ X ≤ 1.3) (Give decimal answer to two places past decimal.) Tries 0/2
c.) P(X > 1.3) (Give decimal answer to two places past decimal.) Tries 0/2
d) Find the median time the book is checked out. (Give decimal answer to two places past the decimal.) Tries 0/2
e) Find the mean time the book is checked out. (Give decimal answer to two places past the decimal.) Tries 0/2
Let , the pdf of X is given by ,
