While ignoring the independent variable,we make 78 errors when predicting the dependent variable.When taking the independent 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 fact that taking the independent variable into account reduces the error in predicting the dependent variable suggests that the two variables are associated. However, we cannot conclude that the independent variable is definitely a cause of the dependent variable based on this information alone. Additionally, we cannot determine the value of phi without knowing more about the nature and measurement of the variables involved.
