I find a handy confirmation is to run . pt(1.96, 1000000, lower.tail = F) * 2. which yields 0.04999607.. Here, we're using the well-known property that 95% of the area under the normal distribution occurs at ~1.96 standard deviations, thus the output of ~0.05 gives our p-value. in which country is the gizeh sphinx located https://amgsgz.com
