The readings recorded from a $20$ -psig pressure gauge are given in the Table. The regression line obtained for the data is $y=0.04~ x+10.32$. The regression coefficient of determination, $R^{2}= \_\_\_\_\_\_$(rounded off to three decimal places).
$\begin{array}{|c|c|c|c|c|c|} \hline x & 1 & 2 & 3 & 4 & 5 \\ \hline y (\text{psig}) & 10.3 & 10.5 & 10.4 & 10.5 & 10.5 \\ \hline \end{array}$
