WebSome idea of the significant value for p-value. In general, 0.05 is used as the cutoff or threshold for significance. This means a p – value that is greater than the significance level indicates that there is insufficient evidence in your sample to conclude that a non-zero correlation exists. small the p-value, stronger the evidence to reject ...

WebJul 22, 2024 · Suppose we want to find the p-value associated with a z-score of 1.24 in a two-tailed hypothesis test. To find this two-tailed p-value we simply multiplied the one-tailed p-value by two. The p-value is 0.2149. If we use a significance level of α = 0.05, we would fail to reject the null hypothesis of our hypothesis test because this p-value is ...
