Question

In testing for differences between the means of two independent populations, the null hypothesis is
A) H₀: μ₁ - μ₂ = 2.
B) H₀: μ₁ - μ₂ = 0.
C) H₀: μ₁ - μ₂ > 0.
D) H₀: μ₁ - μ₂ < 2.

Quizplus · Accepted Answer

The null hypothesis in this scenario is that there is no difference between the means of the two independent populations. Therefore, the correct choice is B, which states that the difference between the means is zero. Choices A, C, and D are all incorrect because they make specific assumptions about the direction or magnitude of the difference between the means.
