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.
