Which F Test Is Used to Test the Significance of the Overall

Short Answer

Which F test is used to test the significance of the overall effect? A) $F = \frac { S S _ { x 1 } / d f _ { n } } { S S _ { e r r o r } / d f _ { d } }$

B) $F = \frac { S S _ { x 1 \times 2 } / d f _ { n } } { S S _ { \text {error } } / d f _ { d } }$

C) $F = \frac { \left( S S _ { x I } + S S _ { x 2 } + S S _ { x 1 } \times 2 \right) / d f _ { n } } { S S _ { e r r o r } / d f _ { d } }$

D) $F = \frac { S S x } { S S _ { \text {error } } / ( N - c ) }$
