• B) \(\frac { \sum \left[ \left( X - M _ { X } \right) \left( Y - M _ { Y } \right) \right] } { \sqrt { \left( S D _ { X } \right) \left( S D _ { Y } \right) } }\)
• C) \(\frac { \sum \left[ \left( X - M _ { X } \right) \left( Y - M _ { Y } \right) \right] } { \left( S S _ { X } \right) \left( S S _ { Y } \right) }\)
