WebOct 20, 2024 · Next, we’ll calculate the degrees of freedom: df = n 1 + n 2 – 2 = 40 + 38 – 2 = 76. Lastly, we’ll plug in the test statistic and degrees of freedom into the T Score to P Value Calculator to find that the p-value is 0.21484. Since this p-value is not less than our significance level α = 0.05, we fail to reject the null hypothesis.
