WebAug 16, 2024 · Otherwise, if the p-value is not less than α = .05 then we fail to reject the null hypothesis and conclude that we do not have sufficient evidence to say that there is a statistically significant difference between the means of the three groups. In this particular example, the p-value is 0.1138 so we would fail to reject the null hypothesis. WebAnd so in this scenario, we do see that 0.036, our p-value is indeed less than alpha.
