Answer:
![H_0 : \mu_1 - \mu_2 = 0](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%3D%200)
![H_a : \mu_1 - \mu_2 \ne 0](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%5Cne%200)
Step-by-step explanation:
Let the salted package be represented with 1 and the unsalted, 2.
So:
Mean of salted package
Mean of unsalted package
Considering the given options, the null hypothesis is that which contains =.
So, the null hypothesis is:
![H_0 : \mu_1 - \mu_2 = 0](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%3D%200)
The opposite of = is
. So, the alternate hypothesis, is that which contains ![\ne](https://tex.z-dn.net/?f=%5Cne)
So, the alternate hypothesis is:
![H_a : \mu_1 - \mu_2 \ne 0](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%5Cne%200)
