How to test the hypothesis in critical value?
To test the hypothesis in the critical value approach, compare the critical value to the test statistic. Unlike the p-value approach, the method we use to decide whether to reject the null hypothesis depends on the form of the hypothesis test.
How to calculate the statistic for hypothesis testing?
The first step in hypothesis testing is to calculate the test statistic. For hypothesis tests about the population mean (μ), the test statistic is z = x ¯ − μ 0 σ / n if the population standard deviation (σ) is known and t = x ¯ − μ 0 s / n if σ is unknown.
