The Following Sums of Squares Are Produced $\Sigma$ (Y_i-(Y-Bar))² = 250 $\Sigma$

question 18

Short Answer

The following sums of squares are produced: $\Sigma$ (y_i-(y-bar))² = 250, $\Sigma$ (y_i-(y_i-hat))² = 100, $\Sigma$ ((y_i-hat)-(y-bar))² = 150
The percentage of the variation in y that is explained by the variation in x is: $\begin{array}{|l|l|}\hline\text { A. } & 60 \% \\\hline \text { B. } & 75 \% \\\hline \text { C. } & 40 \% \\\hline \text { D. } & 50 \% \\\hline\end{array}$
