Decide, at the given significance level, whether the data provide sufficient evidence to conclude that x is useful forpredicting y.
-Decide, at the 10% significance level, whether the data provide sufficient evidence to conclude that x is a useful predictor of y. $$\begin{array} { l | r r r r r } x & 0 & 1 & 5 & 3 & 3 \\ \hline y & 7 & 5 & - 4 & 0 & 1 \end{array} \quad \hat { y } = 7.105 - 2.211 x$$
