Chapter 3.3, Problem 12E

An investment firm offers its customers municipal bonds that mature after varying numbers of years.Given that the cumulative distribution function of T,the number of years to maturity for a randomly selected bond, is

F ( t ) = { 0 , t < 1 , 1 4 , 1 t < 3 , 1 2 , 3 t < 5 , 3 4 , 5 t < 7 , 1 , t 7 ,

find

  1. P(T = 5);
  2. P(T> 3);
  3. P(1.4
  4. P(T = 5 | T = 2).

Given the Cumulative Distribution Function(C.D.F)  F ( x ) = { 0 ,                         x < − 2  (x + 3)/5  ,       − 2 ≤ x < 1.5 1 ,                       1.5 ≤ x  Compute P(x>0)
Let X be the number of microorganisms in a proliferation culture whose Function of Cumulative Distribution (fda) is given by: F(x) = 1 − e−λx, for x > 0. What is the value of λ such that P(X ≥ 10.14) = 0.8
If F(x1, x2, x3) is the value of the joint distribution function of X1, X2, and X3 at (x1, x2, x3), show that the joint marginal distribution function of X1 and X3 is given by M(x1, x3) = F(x1, q, x3) for −q < x1 < q, −q < x3 < q and that the marginal distribution function of X1 is given by G(x1) = F(x1, q, q) for −q < x1 < q With reference to Example 19, use these results to find (a) the joint marginal distribution function of X1 and X3; (b) the marginal distribution function of X1.
