WebOct 4, 2024 · We then calculate the test statistic as follows: t = b / SE b; t = 1.117 / 1.025; t = 1.089; The p-value that corresponds to t = 1.089 with df = n-2 = 40 – 2 = 38 is 0.283. Note that we can also use the T Score to P Value Calculator to calculate this p-value: Since this p-value is not less than .05, we fail to reject the null hypothesis. WebIf the p-value associated with the t-test is not small (p > 0.05), then the null hypothesis is not rejected and you can conclude that the mean is not different from the hypothesized value. In this example, the t-statistic is 4.1403 with 199 degrees of freedom. The corresponding two-tailed p-value is .0001, which is less than 0.05.
