What is another form of the alternative hypothesis when testing the difference between the means of the two groups? A) $\mu$₁ - $\mu$₂ = 0 B) $\mu$₁ - $\mu$₂ $\neq$ 0 C) $\mu$₁ - $\mu$₂ = 2 D) $\mu$₁ - $\mu$₂ $\neq$ 2

The alternative hypothesis in this scenario is typically written as H1: µ1 ≠ µ2, which means that the means of the two groups are not equal. Option B is the closest to this form, as it states that the difference between the means is not equal to zero (i.e. there is a significant difference). Options A and C have a specific number in the equation, which is not appropriate for a general hypothesis. Option D has the correct inequality symbol but also includes a specific number, which is not necessary.
