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 courses consume more alcohol than UMass Amherst recent graduates. * Use hypothesis testing and a confidence interval to test the claim “the mean of days per week and the mean of the amount of alcohol consumed each time one drinks will be greater for UMass students than those who’ve recently graduated” * Establish a connection between the amount of alcohol consumed each time one drinks and the number of days per week alcohol is consumed. The null hypothesis is: the mean of days per week, and mean of amount of alcohol per sitting, is equal for those enrolled at UMass Amherst and recent UMass Alum. This null hypothesis, and all null hypotheses, indicates that there is no change in the two means. The alternative hypothesis which is also the claim in this case is, as stated above, “the mean of days per week and the mean of the amount of alcohol consumed each time one drinks will be greater for UMass students than those who’ve recently graduated from UMass.” I chose this claim because from speaking to fellow recent graduates and witnessing first hand, I find that while in college there is more time to drink and it is a much more alcohol induced atmosphere. One major aspect is the fact that in college Thursday evenings are considered “the weekend” and a big night to go out partying. This increases the amount of days per week a college student parties and could partake in alcohol consumption. Time is also another strong factor in this claim. Majority of college students do not have jobs, or if they do they are part time and not taken seriously. Recent graduates are busy working, finding a job, or even attending/applying to graduate schools. Age is a factor as well. College students are on average younger than recent graduates and can explain some of the immaturity and cause for excessive drinking. This claim takes all of these factors into consideration and will be either proven correct or incorrect based on the results found from a survey conducted. A seven question survey was used to collect the data needed to test this claim. The questionnaire surveyed the population of recently graduated UMass Amherst men and women and current UMass students. I conducted the survey on the campus of UMass Amherst in October 2012 during UMass’s Alumni Weekend. I attended several parties and bars filled with current students and recent graduates and asked thirty current students, as well as, thirty recent graduates to fill out the survey. I made sure to inform them the information would be kept anonymous and also that it was a voluntary survey and they did not have to participate. I finished the collection of data by the end of the Alumni Weekend. It took me Saturday morning – Sunday morning to be able to successfully ask sixty different men and women at UMass to complete the survey. The majority of the completed surveys were done at a bar Saturday afternoon where the recent graduates and current students collaborated to celebrate the alumnae. Overall, the collection of the data was not too difficult. Majority of the people were willing and interested in filling out the survey. I feel as though the sample would accurately represent the two populations. There is a fairly average number of males and females...
