Calculate, test, and interpret the relationship between two variables using the correlation coefficient
Given the following sample observations, draw a scatter diagram on a separate piece of paper.
(1) Compute the correlation coefficient. (Round your answer to 3 decimal places.)
Coefficient of correlation
(2) Does the relationship between the variables appear to be linear?
(3) Try squaring the X- variable and then determine the correlation coefficient. (Round your answer to 3 decimal places.)

Thanks for letting me work on your post. Here is my explanation:
mean of x=(-8-18+14+5+18)/5=2.2
mean of y=(57+257+140+9+348 ...
This solution interprets the relationship between two variables.
