While ignoring the independent variable, we make 78 errors when predicting the dependent variable. When taking the independent variable into account, we reduce the number of errors to 43. Therefore________.
A) the variables are not associated
B) the variables are associated
C) the independent variable is definitely a cause of the dependent variable
D) phi will be 0.

The decrease in errors when taking the independent variable into account suggests that the variables are associated. However, we cannot conclude that the independent variable is definitely a cause of the dependent variable without further information or analysis. Phi, a measure of association, cannot be determined with only the given information.
