The null hypothesis for a repeated-measures test states that ____. A)each individual will have a difference score of D = 0 B)the overall sample will have a mean difference of M_D = 0 C)the entire population will have a mean difference of μD = 0 D)the individuals have different means

The null hypothesis for a repeated-measures test states that there is no significant difference between the mean scores or measures on the same group of individuals under different conditions or at different points in time. This means that the entire population will have a mean difference of μD = 0. Option A is correct for a one-sample t-test, not a repeated-measures test. Option B is not the correct formula for the null hypothesis. Option D is incorrect because the individuals being tested are the same, so they cannot have different means.
