If SSR =4 and SSE = 16, determine SST, then compute the coefficient of determination, r, and interpret its meaning. SST= 12 =(Type an integer or a decimal. Do not round.) Interpret the meaning of r2. Choose the correct answer below. O A. It means that 2 . 100% of the variation in the dependent variable can be explained by the variation in the independent variable. O B. It means that (1-r2) . 100% of the variation in the independent variable cannot be explained by the variation in the dependent variable. O C. It means that 2 of the variation in the independent variable can be explained by the variation in the dependent variable. O D. It means that 1 -12 of the variation in the dependent variable cannot be explained by the variation in the independent variable
