Which of the following four statements is correct?

Let f(x) = 2 + 5x be a linear regression line of a linear regression from Y to X.

Then the following holds for the scatter plot:

1- The closer the points in the scatter plot lie to the plotted regression line the stronger the correlation between X and Y .

2- The further the points in the scatter plot are from the plotted regression line the stronger is the correlation between X and Y .

3- Only if all points lie exactly on the plotted regression line, the correlation between X and Y is the correlation between X and Y is strong.

4- The position of the points in the scatter plot has nothing to do with the strength of the correlation.
