WebJun 6, 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.
