This gives us .3085. Because this is two-tail hypothesis testing, we double this value and get 0.617 or 61.7%. A point to know is that p-values are probabilities; therefore, they must be between 0 and 1. The p-series test is a great test for quickly finding convergence for this special series type. Even the harmonic series follows the test; The series diverges for p = 1. Just make sure that the series you're trying to evaluate follows the general formula.How do you find the p-value of a two tailed test when z = 1.95?
