Quizplus · Accepted Answer

In testing for differences between the means of two independent populations, the null hypothesis states that there is no difference between the means. This is usually written as H0: µ1 - µ2 = 0, where µ1 and µ2 are the means of the two populations. Therefore, the correct null hypothesis is H₀ : μ₁ - μ₂ = 0. Option B is the only one that correctly represents the null hypothesis.
