Homework Answers
Here'the answer to the question. Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer
We have the =CORREL formula in Excel to take out the r or the correlation
Rsquare/r^2 is basically the square of the correlation.
Values of correlation (r) and R-square(r^2) are in red.
