In comparing the difference of the means between two groups,the null hypothesis can also be stated as ____.
A)µ₁ - µ₂ = 0
B)µ₁ + µ₂ = 0
C)µ₁ x µ₂ = 0
D)µ₁ / µ₂ = 0

Question

Quizplus · Accepted Answer

The null hypothesis when comparing the difference of means between two groups is typically that there is no difference, which can be expressed as the difference of the two population means (µ₁ - µ₂) equaling zero. Therefore, option A is the correct answer. Option B adds the two means together, which is not appropriate. Option C multiplies the means together, which is also not appropriate. Option D divides the means, which again is not appropriate.
