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.

WebA test statistic is a statistic (a quantity derived from the sample) used in statistical hypothesis testing. [1] A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data-set that reduces the data to one value that can be used to perform the hypothesis test. WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that …
