this is the problem

(10 points) Heights (in centimeters) and weights Gn kilograms) of 7 supermodels are given below. Height (x) 172 166 178 174 172 176 176 Weight(y) 52 47 58 55 53 54 55 (Note: Compute values to three decimal places of accuracy.) The regression equation is y = Regardless of what answer you actually got, suppose your regression equation were y = -80+ 0.8 x. This line predicts the weight of a supermodel who is 167 cm tall to be kg
