WebP-value Formula. We Know that P-value is a statistical measure, that helps to determine whether the hypothesis is correct or not. P-value is a number that 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 WebThe formula for a one-tailed binomial test is: p-value = P (X ≥ k), where X is the number of successes, k is the number of observed successes (51), and P is the probability of success (0.5). Using this formula, the p-value was calculated to be 0.049, which is less than the significance level of 0.05. Therefore, we can reject the null ...
