A pair of variables, x and y, have a correlation coefficient of -0.5. How much of the variation in y is explained by the variation in x ( by the model) [as a percentage]? Note: 1- First convert your answer to the percentage and then round to 1 decimal place. Enter your final answer with 1 decimal place. 2- State the answer as a percentage without the percentage $. For instance, if the answer is 24.5%, only enter 24.5. Your Answer: Answer

The correlation between two variables x and y is -0.6. If we used a regression line to predict y using x, what percent of the variation in y would be explained?

Use the value of the correlation coefficient $r$ to calculate the coefficient of determination $r^{2}$. What does this tell you about the explained variation of the data about the regression line? About the unexplained variation? $$r=-0.957$$
