for the following information, find the regression equation y hat

n=4                                       Ex=10                    Ey=20

Ex² =36                               Ey²=120                 Exy=48

A. (use four decimal places for your equation values) y hat=?

B. given that X equals 12, find the best predicted value of Y. Use four decimal places.

C. y=
