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. WebAlpha, the significance level, is the probability that you will make the mistake of rejecting the null hypothesis when in fact it is true. The p-value measures the probability of getting a more extreme value than the one you got from the experiment. If the p-value is greater than alpha, you accept the null hypothesis. chiswick business park building 11Webmethod. This is an iterative procedure beginning with a range of $\alpha$ between 0.1 and 0.9.
