Question

Suppose we suspect that the average means, $LaTeX: \mu_1$ μ 1 and $LaTeX: \mu_2$ μ 2, of two populations are different. What is an appropriate alternative hypothesis for this situation?

Group of answer choices

$LaTeX: H_A: \mu_1 \neq \mu_2$ HA:μ1≠μ2

None are correct

$LaTeX: H_A: \mu_1 = \mu_2$ HA:μ1=μ2

$LaTeX: H_A: \mu_1 \geq \mu_2$

Answer 1

We need to test if population means are different. Hence,

Our alternative hypotheses will be:

$LaTeX: H_A: \mu_1 \neq \mu_2$

Option A is correct.
