WebFor a population proportion test, the test statistic is a Z-Value from a standard normal distribution. Because this is a two-tailed test, we need to find the P-value of a Z-value smaller than -8 and multiply it by 2. We can find the P-value using a Z-table, or with a programming language function: Example.
