A pair of variables, x and y, have a correlation coefficient of -0.7. How much of the variation in y is explained by the variation in x ( by the model) [as a percentage]? 1) First convert your answer to the percentage and then round to 1 decimal place. Final answer should be with 1 decimal place. 2) State the answer as a percentage.
