Statistical Analysis Consumption of Alcohol by...

Kristen Petreyko Statistics: MA 105 Statistics Project Due: December 17, 2012 INTRODUCTION Being a recent graduate of the University of Massachusetts Amherst, I have found that a person’s whole lifestyle changes with the simple act of graduating college. One of the most obvious lifestyle modifications for many recent graduates is the decrease in the amount of partying, and the realization that it ends when college does. I conducted a statistical analysis on the consumption of alcohol for those still enrolled in undergraduate programs compared to the consumption of recent graduates. My research objectives include the following: * Document with statistical evidence that UMass Amherst students currently enrolled in†¦show more content†¦The majority of the college students were seniors and juniors, although some freshmen and sophomores were surveyed. Statistically, a voluntary response sample, which is when the respondents chose to participate or not, is not considered a sample that cannot be used to make conclusions about a population so in conclusion, this sa mple should not be used to make a conclusion about the population of UMass students or UMass recent graduates. BODY OF THE PROJECT The hypothesis of what is expected is that as a whole UMass Amherst college students will consume more alcohol than UMass Amherst recent graduates. In particular, the mean of the days per week alcohol is consumption and the mean of the amount of alcohol drank each day one drinks will be greater for UMass Amherst students than the means of UMass Amherst recent graduates. I am interested in calculating if the average amount of alcohol each time one drinks is exceptionally higher for those in college than not. Also, if the days per week correspond to the amount drank and if the mean of days per week and mean of amount drank will differ for students and/or alumni. RESULTS Descriptive Statistical Analysis Consumption of alcohol (days per week): | UMass Amherst Current Students (n=35) | UMass Amherst Recent Graduates (n=35) | Mean: Mean= | Mean=3.357 days per week | Mean=2.643 days per week | Median: Median=Center value when arranged in increasing orderShow MoreRelatedHistory Of Caffeinated Energy Drinks2540 Words   |  11 Pagesof caffeine in a single serving. Although current research suggests that adults can consume up to 400 mg of caffeine per day safely, many people consume more than one serving of these CEDs and they may be exceeding the limit of safe consumption [4].
