The correlation coefficient (r) between the number of volunteers x and the number of bags of trash collected y is 0.654 what percent of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers?

42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.

Step-by-step explanation:

The correlation coefficient (r) between the number of volunteers x and the number of bags of trash collected y is 0.654

For finding the percent of the variation in one variable explained by the other variable, we just need to take square of the correlation coefficient.

Here,  

So,  

Now, for converting it into percentage, we will multiply it by 100.

So,

Thus, 42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.

c. (3,2,6) is the answer.
