Suppose You Will Perform a Test to Determine Whether There $\alpha$

Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear
correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance
level $\alpha$
-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. $$\begin{array} { | c | c c c c l } \hline x & 1.2 & 2.7 & 4.4 & 6.6 & 9.5 \\\hline y & 1.6 & 4.7 & 8.9 & 9.5 & 12.0 \\\hline\end{array}$$
