Answer:
c. Their correlations are the same, but the equations are different
Explanation:
The formula for the correlation coefficient of two variables is symmetrical: it is unchanged when the variables are interchanged. This means Juan and Belle will both calculate the same correlation coefficient.
The formulas for the linear regression equation depend on the choice of dependent and independent variable. Since Juan and Belle have made opposite choices for those, their equations will be different. (Each function will be the inverse of the other.)
The appropriate description is found in choice C.
