Explanation / Answer

As we have got the value of correlation coefficient of graduation v/s minority rate and that is -0.624 and to find the explaination of variance we must know the value of r^2 and that is nothing but Square of the correlation and i.e.

R^2= -0.624 * - 0.624 = 0.389376

and so here we can say that 38.94% of variation in graduation rate is attributed to school's minority pecentage

Hope the above explaination has helped you in understanding the problem Pls upvote the ans if it has really helped you. Good Luck!!
