If
X = 0.85, n = 100, and σ2 = 25, find the p–value for the test of the hypothesis

H0 : μ = 0 vs. H1 : μ (not=)0.


I understand how to perform the test, just not how to calculate the p value. I know the theory, just need a practical example. If anyone could do this question that would be great. Thanks
