Answer:
51% of the variation in Y is not explained by the regression line.
Step-by-step explanation:
To find the amount of variation not explained by the regression equation (how you found the correlation coefficient), we need to find <em>R. </em>We already have r ...
So to find R from r ( the correlation coefficient ) we just square it.
r² = .7² = .49
Then we just subtract that number from 1 to get the amount of <em>variation that is </em>not explained - which is ... .49 - 1 = .51 (convert to percent) = 51%
