             d.   heteroscedasticity

            e.         multicollinearity

All of the following are reasons why an association relationship may not imply a causal relationship except:

             a.   the association may be due to pure chance

             b.   the association may be the result of the influence of a third common factor

Consumers will be in equilibrium with respect to the consumption of two goods if:

             b.   the marginal utility of the lowest price good is greater than the marginal utility of the highest price good.

             c.    the ratio of the marginal utility of A to the marginal utility of B is equal to the ratio of the price of B to the price of A.

             d.  the marginal utility of both goods is identical, regardless of the price.
