1. Refer to Exercise 30. An equation to predict the ductility of a titanium weld is Y = 7.84C + 11.44N + O _ 1.58Fe, where Y is the oxygen equivalence used to predict ductility, and C, N, O, and Fe are the amounts of carbon, nitrogen, oxygen, and iron, respectively, in weight percent, in the weld. Using the means, standard deviations, and correlations presented in Exercise 30, find Y and _Y 2. Let X and Y be jointly continuous with joint probability density function f(x, y) and marginal densities fX (x) and fY (y). Suppose that f(x, y) = g(x)h(y) where g(x) is a

Using the means, standard deviations, and correlations presented in Exercise 30, find Y and _Y 2. Let X and Y be jointly continuous with joint probability density function f(x, y) and marginal densities fX (x) and fY (y). Suppose that f(x, y) = g(x)h(y) where g(x) is a function of x alone, h(y) is a function of y alone, and both g(x) and h(y) are nonnegative. a. Show that there exists a positive constant c such that fX (x) = cg(x) and fY (y) = (1/c)h(y). b. Use part (a) to show that X and Y are independent.
