If SSR = 10 and SSE = 40, determine SST, then compute the coefficient of determination, re, and interpret its meaning. SST =\fInterpret the meaning of r2. (Choose correct answer below} a.) It means that r2 of the variation in the independent variable can be explained by the variation in the dependent variable. b.) IT means that 1-r2 of the variation in the dependent variable cannot be explained by the variation in the independent variable. C.} It means that (1r2]. 100% of the variation in the independent variable cannot be explained by the variation in the dependent variable. d.) It means that r2. 100% of the variation in the dependent variable can be explained by the variation in the independent variable
