Essay

Consider the following data for two variables, x and y. $$\begin{array} { | c | c c c c c c c c c c | } \hline x & 7 & 10 & 3 & 5 & 3 & 10 & 4 & 14 & 5 & 8 \\\hline y & 35.0 & 28.5 & 45.0 & 45.0 & 55.0 & 25.0 & 37.5 & 27.5 & 30.0 & 27.5 \\\hline\end{array}$$ Use Excel to determine whether there is sufficient evidence at the 1% significance level to infer that the relationship between y, x and $x ^ { 2 }$ in $\hat{y}$ = 66.799-7.307x + 0.324x² is significant.
