Answer:
64%
Step-by-step explanation:
The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:
First, square the coefficient of correlation: 0.8^2 = 0.64
And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
The point-slope form:
We have the points (-5, 15) and (20, 25). substitute:
