• B) \(\frac { R S S } { T S S }\)
• C) \(\frac { \sum _ { i = 1 } ^ { n } \left( Y _ { i } - \bar { Y } \right) \left( X _ { i } - \bar { X } \right) } { \sqrt { \sum _ { i = 1 } ^ { n } \left( Y _ { i } - \bar { Y } \right) ^ { 2 } } \sqrt { \sum _ { i = 1 } ^ { n } \left( X _ { i } - \bar { X } \right) ^ { 2 } } }\)
• D) \(\frac { S S R } { n - 2 }\)
