Given that :

the null and the alternative hypothesis are computed as :

H_o: \mu_1 = \mu_2

H_a : \mu _1 \neq \mu_2

This is a two tailed test

This is because of the ≠ sign in the alternative hypothesis which signifies that the rejection region in the alternative hypothesis are at the both sides of the hypothesized mean difference .

Decision Rule: at the level of significance ∝ = 0 . 10

The decision rule is to reject the null hypothesis if z < - 1 . 64 and z > 1 . 64
