Answer:
![H_o:\mu = 26](https://tex.z-dn.net/?f=H_o%3A%5Cmu%20%3D%2026)
![H_a:\mu < 26](https://tex.z-dn.net/?f=H_a%3A%5Cmu%20%3C%2026)
Step-by-step explanation:
Given
Average score is less than 26
Required
Determine the null and alternate hypothesis
Since the average is said to be less than 26; that represents the alternate hypothesis.
The null hypothesis will be:
![Average = 26](https://tex.z-dn.net/?f=Average%20%3D%2026)
So, we have:
![H_o:\mu = 26](https://tex.z-dn.net/?f=H_o%3A%5Cmu%20%3D%2026)
And the alternate hypothesis
![H_a:\mu < 26](https://tex.z-dn.net/?f=H_a%3A%5Cmu%20%3C%2026)
