You are conducting the following hypothesis test for mean age of a certain population. when population standard deviation is known. H0: µ = 47, H1: µ > 47 The z test statistic from a sample of n = 30 observations was calculated and it was z = 2.04. Based on this information what is the p-value of this test?

You are conducting the following hypothesis test for mean age of a certain population. when population standard deviation is known. H0: µ = 47, H1: µ > 47 The z test statistic from a sample of n = 30 observations was calculated and it was z = 2.04.
Instead of doing one-sided test in the above problem, we decided to use the following two-sided test: H0: µ = 47, H1: µ ≠ 47 The z test statistic from a sample of n = 30 observations was calculated and it was z = 2.04. Based on this information what is the p-value of this test?
