Webb6 juni 2024 · The calculator returns the cumulative probability, so to find the p-value we can simply use 1 – 0.98303 = 0.01697. Since the p-value (0.01697) is less than our alpha level of 0.05, we reject the null hypothesis of our test. We have sufficient evidence to say that our results are statistically significant at alpha level 0.05. Webb5 sep. 2024 · p-value is the cumulative probability (area under the curve) of the values to the right of the red point in the figure above. Or, p-value corresponding to the red point tells us about the ‘total probability’ of getting any value to the right hand side of the red point, when the values are picked randomly from the population distribution.

Webb22 jan. 2024 · This means that the p-value for a one-sided test is between 0.1 and 0.05. Let’s call it .075. Since our t-test is two-sided, we need to multiply this value by 2. So, our estimated p-value is .075 * 2 = 0.15. Step 4: Draw a conclusion. Since this p-value is not less than our chosen alpha level of .05, we can’t reject the null hypothesis.
