The sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0, the results tend to
<h3>How to interpret Garret studies?</h3>
From the question, we have the following highlights
- The sample size is large enough
- The sample is at random
- Students who have a grade point average of 3.0 - 4.0 sleep for an average of 6.8 hours
- Students who have a grade point average of 2.0–3.0 sleep for an average of 6.4 hours
- There are no outliers
From the above highlights, the sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0
This is because 6.8 is greater than 6.4
This means that Garret's theory about the hours of sleep is correct
