For some of the attributes in your computer decision, you face uncertainty. The additive utility function assessed in Problem 15.17 essentially assumes that additive independence among attributes is reasonable.
a. Check some of your attributes with formal assessments for additive independence. Follow the example in the text in setting up the two lotteries. (One lottery is a 50-50 gamble between best and worst on both attributes. The other is a 50-50 gamble be- tween (i) best on X, worst on Y; and (ii) worst on X, best on Y)
b. How could you extend this kind of assessment for additive independence to more than two attributes?
