The Friedman test is used to determine if there is a significant difference between treatment levels. Therefore, since the question is asking about the significance of the treatments, we need to look for the null hypothesis that there is no difference between the treatments. The null hypothesis in this case is that the treatment populations are equal. Therefore, if we do not reject the null hypothesis with α = 0.05, we can conclude that there is not enough evidence to say that there is a significant difference between the treatments. Hence, the appropriate conclusion is do not reject H₀: the treatment populations are equal.
