The null hypothesis for a repeated-measures test states that the entire population will have a mean difference of μ_D = 0. Option A refers to each individual having a difference score of zero, which is not the correct wording for the null hypothesis. Option B is incorrect because it refers to the sample, not the population. Option D is incorrect because all options are not correct – only option C is the correct statement of the null hypothesis.
