The correlation coefficient between two variables x and y is r = 0.121. What conclusioncan we draw?

A) Because the correlation is so low, the relationship between x and y is not very strong,thus there is no use in studying this relationship

.B) Because the correlation is so low, we only know that the linear relationship between xand y is not very strong, but there may be a different relationship between the twovariables. We need to first look at a scatterplot.

C) The correlation between x and y is low, but that does not matter. We can still use least squares regression to calculate an equation of the form y = ax + b.

D) None of the above.

Can someone explain this question with details for each choice? Thanks!
