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 = 2. C) H₀ : µ₁ - µ₂ = 0. D) H₀ : µ₁ - µ₂ > 0.

Quizplus · Accepted Answer

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 0. Therefore, choice C (H0 : µ1 - µ2 = 0) is the best choice for the null hypothesis. Choices A, B, and D are either incorrect or not appropriate for this type of hypothesis test.
