How to look for the critical value of Pearson Correlation?

[is_919]

Hi!

How do I compute (using only TI-84) for the critical value of the Pearson Correlation Coefficient "r" without using the table?

An example would be: What is the critical value corresponding to n = 45 and a significance level of a = 0.01. Also given is r = 0.354

If you can compute t-distribution critical points, you can use \(\displaystyle t = r \frac{\sqrt{n-2}}{\sqrt{1-r^2}}\) which has a t-distribution with \(\displaystyle n-2\) degrees of freedom.
