Here is How to Find the P-Value from the t-Distribution Table
https://www.statology.org/here-is-how-to-find-the-p-value-from-the-t-distribution-table/
WEBJun 6, 2019 · If you are interested in finding the t critical value for a given significance level, degrees of freedom, and type of test (one-tailed or two-tailed), then you should use the t distribution table. Instead, if you have a given test statistic t and you simply want to know the p-value of that test statistic, then you would need to use a T Score to ...

WEBJan 22, 2020 · Solution: Step 1: State the null and alternative hypotheses. H0: µ = 15. Ha: µ ≠ 15. Step 2: Find the test statistic. t = (x-μ) / (s/√n) = (14-15) / (3/√20) = -1.49. Step 3: Find the p-value for the test statistic. To find the p-value by hand, we need to use the t-Distribution table with n-1 degrees of freedom.
