The null hypothesis for testing differences between the means of two independent populations is typically that the difference between the population means is equal to zero. The null hypothesis is usually denoted as H0: μ1 - μ2 = 0, where μ1 and μ2 are the population means of the two populations being compared. Choice A is the closest option to this typical null hypothesis, as it has the same format with the specific populations denoted as ₁ and ₂.
