               c) regression equation for Y on X for standard scores?

                       The  regression  equation  for  Y  on  X  for  standard  score  is
               defined as,
                                         Z y’ = (r xy)(Z x)

                       Where r xy correlation between x and y

                                                   ∑
                                                    −
                                                √ ∑     √ ∑
                                                  −     −



                                               √       √



               Thus, regression equation for Y on X for standard score is

                              Z y’ = (0.80)(Z x)


               d) regression sum of squares?

                                                           ̅
                       Regression sum of square =   SS reg=∑ (Y' -  ) 2   = 22.964
