Answer:
Step-by-step explanation:
Given that :
the null and the alternative hypothesis are computed as :
![H_o: \mu_1 = \mu_2](https://tex.z-dn.net/?f=H_o%3A%20%5Cmu_1%20%3D%20%5Cmu_2)
![H_a : \mu _1 \neq \mu_2](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu%20_1%20%5Cneq%20%5Cmu_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
