Question: 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

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 μY and σY.
