Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Find the regression equation, letting height be the explanatory (x) variable, and predict the weight of a supermodel who is cm tall.

Height: 174 176 178 178 172 174 168

Weight: 54 54 57 58 52 55 50

The regression equation is y^= .

(Note: Please give at least three decimal places of accuracy in your equation.)

The best predicted weight of a supermodel who is 169 cm tall is kg.

(Note: Use at least three decimals of accuracy when calculating your answer.)
