Critical value to p value
WebUse this method to find the p-value for a one-sided z-test with the critical region in the right tail. In this testing scenario, the result is the p-value. For the apple example above, the z-table indicated that the area below z = 0.67 was 0.74857. 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.
