WebFinal answer. Assume that both populations are normally distributed. Test whether μ1 = μ2 at the α = 0.05 level of significance for the given sample data Test whether μ1 = μ2 at the α = 0.05 level of significance for the given sample data Determine the null and alternative hypothesis for this test. A. H0μ1 = μ2 H1μ1 = μ2 B. H0μ1 ... 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.
