Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Find the regression equation, letting the first variable be the independent (x) variable, and predict the weight of a supermodel who is 171 cm tall.

 

\begin{array}{c|ccccccc}

\mbox{Height} & 174 & 166 & 176 & 176 & 178 & 172 & 172 \cr

\hline

\mbox{Weight} & 55 & 47 & 55 & 56 & 58 & 52 & 53 \cr

\end{array}

The regression equation is \hat{y} = 

 + 

 x . The best predicted weight of a supermodel who is 171 cm tall is
