Mission Statement
We realize that alcohol can play a huge role on the performance of a college student. We conducted a survey with 13 questions which asked 75 business students questions about how much alcohol they consume and how it effects their schoolwork.

Hypothesis
For our research, we decided to answer the question whether or not alcohol affects students’ performance in school. We set out to find if there is any correlation between various alcohol related factors and students’ GPA.Null Hypothesis: Students who drink more than
5 nights a week will have a GPA lower than 3.0.Alternative Hypothesis: Students who drink more than 5 nights a week can have a GPA higher than 3.0. H₀ = µ ≤ 3.0 HA = µ > 3.0

Response of the Correlation regarding number of nights drinking and Students’ GPA’s
There is a positive relation between the number of nights a student drinks, and their GPA.
When comparing these results to our hypothesis, we found that the number of nights a student drinks during a week did negatively affect students’ GPA.
As the number of nights per week a student drinks, the more their GPA decreases.

Regression Analysis
We completed a regression analysis comparing the number of nights students drink alcohol to their GPA.
The dependant variable (y) was the students’ GPA
The independent variable (x) was the number of nights students consume alcohol in a week.

Conclusion Overall, we concluded to
not reject our null hypothesis.
Over 57% of the students who drank over 5 nights a week have a GPA of less than 3.0.

Improvements Next time would improve:
By increasing our sample size.
Have more specific questions; not using ranges. Ex. (1-2 drinks, 3-4 drinks)
Decrease the amount of questions in our survey.
Lastly…

• Make sure you team up with reliable teammates, who don’t drop the class with one week left of school.
