WebThe critical value for a one-tailed or two-tailed test can be computed using the confidence interval. Suppose a confidence interval of 95% has been specified for conducting a hypothesis test. The critical value can be determined as follows: Step 1: Subtract the confidence level from 100%. 100% - 95% = 5%. WebIn the p-value approach, the test statistic is used to calculate a p-value. If the test is a lower tail test, the p-value is the probability of getting a value for the test statistic at least as small as the value from the sample. ...
