If we state one hypothesis only and the aim of the statistical test is to see whether this hypothesis is tenable, but not to investigate other specific hypotheses, then such a test is called a null hypothesis test.

Webb22 jan. 2024 · This means that the p-value for a one-sided test is between 0.1 and 0.05. Let’s call it .075. Since our t-test is two-sided, we need to multiply this value by 2. So, our estimated p-value is .075 * 2 = 0.15. Step 4: Draw a conclusion. Since this p-value is not less than our chosen alpha level of .05, we can’t reject the null hypothesis.
