Essay

a. Complete the table.
$\begin{array} { | l | c | c | c | c | } \hline & x _ { i } & y _ { i } & x _ { i } ^ { 2 } & x _ { i } y _ { i } \\\hline & 2 & 3 & & \\\hline & 5 & 2 & & \\\hline & 3 & 4 & & \\\hline & 8 & 0 & & \\\hline \text { Totals } & \Sigma x _ { i } = & \Sigma y _ { i } = & \Sigma x _ { i } ^ { 2 } = & \Sigma x _ { i } y _ { i } = \\\hline\end{array}$

b. Find $S S _ { x y } , S S _ { x x } , \beta _ { 1 } , \bar { x } , \bar { y }$ , and $\hat { \beta } _ { 0 }$ .
c. Write the equation of the least squares line.
