WebApr 23, 2024 · Null hypotheses. This technique actually tests four null hypotheses. The first statistical null hypothesis is that the numbers within each experiment fit the expectations; for our arm-folding example, the null hypothesis is that there is a \(1:1\) ratio of \(R\) and \(L\) folders within each ethnic group.
