# Hypothesis testing for mean

I am looking at this problem that suggests that people will follow a 24 hour cycle of sleeping and waking even if they are not exposed to the usual pattern of sunlight.

Their cycles at the end of the study were 25, 27, 25, 23, 24, 25, 26, and 25.

If we use the 5% level of significance what would we conclude about the theory that 24 hours is the natural cycle.

How would we use the steps of hypothesis testing to do this and sketch the distributions involved.
