question 9

Multiple Choice

Which F test is used to test the significance of the overall effect?

• A) F =\[\frac { S S _ { x 1 x } 2 / d f _ { n } } { S S _ { \text {error } } / d f _ { d } }\]
• B) F =\[\frac { S S _ { X } / ( c - 1 ) } { S S _ { \text {error } } / ( N - c ) }\]
• C) F =\[= \frac { \left( S S _ { x 1 } + S S _ { x 2 } + S S _ { x 1 \times 2 } \right) \left( d f _ { n } \right. } { S S _ { c r r o r } / d f _ { d } }\]
• D) F =\[\frac { S S _ { x } 1 / d f _ { n } } { 5 S _ { e r r o v } d f _ { d } }\]
