Detailed explanation-1: -For example, in an upper tailed Z test, if =0.05 then the critical value is Z=1.645.
Detailed explanation-2: -If the p-value is greater than alpha, you accept the null hypothesis. If it is less than alpha, you reject the null hypothesis.
Detailed explanation-3: -In the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there’s no difference between the means and conclude that a significant difference does exist.
Detailed explanation-4: -The most commonly used significance level is = 0.05. For a two-sided test, we compute 1-/2, or 1-0.05/2 = 0.975 when = 0.05. If the absolute value of the test statistic is greater than the critical value (0.975), then we reject the null hypothesis.
