WebJan 22, 2024 · P-value. P-value is used to find extreme values when the null hypothesis (h 0) is true. In simpler words, it is used to reject or support the null hypothesis during hypothesis testing. In data science, it gives valuable insights on the statistical significance of an independent variable in predicting the dependent variable. Web, the p-value = 0.03, then the probability of randomly selecting a sample of 100 users who spend, on average, 25 minutes on the yellow-background website is only 3%! In other words, the likelihood of getting a sample mean of 25 given that all sample means should be near 20 is only 3%. So, in a world where the null hypothesis is true--a hypothetical world …

P0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z value obtained.
