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. According to the T Score to P Value Calculator, the p-value associated with t = -3.4817 and degrees of freedom = n-1 = 40-1 = 39 is 0.00149. WebThe formula for the calculation for P-value is. Step 1: Find out the test static Z is. z = p ^ − p 0 p o ( 1 − p 0) n. Where, p ^ = Sample Proportion. P0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z value obtained. folded hexies
