WebCalculate the test statistic and the critical value (t-Test, F-test, z-Test, ANOVA, etc.). Calculate a p value and compare it to a significance level (a) or confidence level (1-a). Interpret the results to determine if you "cannot reject null hypothesis (accept null hypothesis)" or "reject the null hypothesis." Web4. Calculating the Test Statistic. The test statistic is used to decide the outcome of the hypothesis test. The test statistic is a standardized value calculated from the sample. The formula for the test statistic (TS) of a population proportion is: \(\displaystyle \frac{\hat{p} - p}{\sqrt{p(1-p)}} \cdot \sqrt{n} \)
