Given the values in the table in the image attached, how do I find the value of r^2? Does the value suggest that the model is a good, somewhat good, or bad fit? About what percent of the total variation in y can be explained by the model? What percent is unexplained?

Question

Given the values in the table in the image attached, how do I find the value of r^2?

Does the value suggest that the model is a good, somewhat good, or bad fit?

About what percent of the total variation in y can be explained by the model? 

What percent is unexplained?

In the previous question you should have been given an r? value of
[ Select ]
1. This particular value suggests that the model is a
[ Select ]
fit. In this particular problem it means that roughly
[ Select ]
percent of the total variation in y can be explained by the model,
and [Select ]
percent is unexplained.
