Multicollinearity exists when which of the following conditions is present? Select one a. The underlying value of the coefficient can only be explained in relation to dependent variables b. Two or more independent variables are highly correlated with each other c. There are two or more statistically significant observations of at least two independent variables d. There are at least two cost pools (usually separated for fixed and variable costs). e. At least two variables change due to changes in the cost driver A coefficient of correlation of x indicates multicollinearity Select one: =0.3 >=0.3 =0.7 =2.0
