WebP-value is an important statistical measure, that helps to determine whether the hypothesis is correct or not. P-value always only lies between 0 and 1. The level of significance(α) is a predefined threshold that should be set by the researcher. It is generally fixed as 0.05. The formula for the calculation for P-value is: WebApr 22, 2024 · We will perform the one sample t-test with the following hypotheses: Step 3: Calculate the test statistic t. Step 4: Calculate the p-value of the test statistic t. …
