Question 384421: 8 students are confined in a room for 30 days with no sunlight. At the end of the experiment their cycle change to 25, 27, 25, 23, 24, 25, 26, and 25. What can you conclude about the 24 hour cycle? Use the steps of hypothesis testing and sketch the distributions involved.
This is my hard question can you please help me? Thanks for you time!

-----------
Ho: u = 24
Ha: u is not equal to 24
-----
The mean of the sample = 25; std of the sample = 1.195229
---
test stat: t = 2.3664
p-value = 0.0499
----
Strict interpretation:
Since the p-value is less than 5%, reject Ho.
---
Reasonable interpretation:
Since the p-value is so close to 5% continue. testing.
