Pearson’s correlation coefficient, r=0.0841 approx.

The regression coefficient is 0.00175 approx. This is used for finding Y given X. The inverse (to find X given Y) is approx 570.3.

The linear equation is Y=1.408+0.00175X.

For X=20, Y=1.44. The correlation is weak because r is small.

The point (140,1.1) is the “stray”.
