For the Data Below, Determine the Value of the Linear $$\begin{array} { l | l c c c l } \mathrm { x } & 1.2 & 2.7 & 4.4 & 6.6 & 9.5 \\\hline \mathrm { y } & 1.6 & 4.7 & 8.9 & 9.5 & 12.0\end{array}$$

For the data below, determine the value of the linear correlation coefficient r between y and ln x and test whether the linear correlation is significant. Use a significance level of 0.05. $$\begin{array} { l | l c c c l } \mathrm { x } & 1.2 & 2.7 & 4.4 & 6.6 & 9.5 \\\hline \mathrm { y } & 1.6 & 4.7 & 8.9 & 9.5 & 12.0\end{array}$$
