According to the information provided above, sleep and stress are correlated, as it suggests that a lack of sleep can lead to stress in psychology students, and the absence of stress is an indication that the psychology student has had a good night’s rest.

The average perceived stress score (PSS) among students in the sample was 26.30 scores.
On average females slept 5.18 hrs and males 6.25 hrs per night. While it appears that males slept more than females , the independent t-test indicated that difference in the means were not significantly different with a 95% CI: (-2.6252, 0.585) where the interval included the possiblity of zero.
It is however important to note that there is a strong negative correlation between perceived stress scores and hours slept per night, r = -0.976 (p = < 0.001) indicating that as stress increases the number of hours slept per night decreases.

I used R. It used a Welch two-sample t-test, where t = -1.6174 and p = 0.1528. So, since p is greater than 0.05, then it’s not statistically significant. The mean sleep for females was 5.17 hours while the mean sleep for males was 6.25 hours. There was a strong negative correlation of -0.97 between pss score and hours slept.

1. What is the average average perceived stress Score was
26.3

2. Did males or females sleep more on average?

On average females slept for 5.18 hours and males 6.25 per night it showed that males slept more than females however T- Test determined that the mean difference was not significantly different a 95% confidence interval resulting in a test value of 0

3. Is there a relationship between stress and sleep what does the correlation suggest?
There was a strong negative correlation of (-0.97) between PSS Score and Sleep hours
Making it negative 0.001 Showing as one variable Increase the other one decreases
