Past research at universities across the country has shown that college students consume an average of 2.5 drinks per week. Administrators at WhatEver University (WEU) have been very concerned about drinking on campus. They conducted a survey in order to determine the drinking habits of students at WEU.
Run the appropriate statistical test to answer the following questions (hint: it will be one of the statistical tests discussed in class and provided in the Statistical Significance & Interpreting Statistics Powerpoint notes).
1. The university administration believes that there is a significant difference in the reasons why people drink between males and females. In one sentence, identify if there is a significant difference between males and females (be sure to provide the appropriate statistics and p-values). What percentage of males say they drink alcohol because it’s the only way to have a good time? What percentage of females drink because they enjoy the taste?
2. Melody, the bartender at the local watering hole, believed that student preferences differed for shots depending on how they classified themselves in terms of drinking (non-drinker, social drinker, moderate drinker, heavy drinker). In one sentence, identify if there is a significant difference in the preference for shots by drinking self classification (be sure to provide the appropriate statistics and p-values). If there are any significant differences, what are they? Who likes shots the most?
3. The President of the University believes that, based on conversation with the head of the police department, WEU students drink far more than the national average. In one sentence, identify whether or not WEU students differ from the national average (be sure to provide the appropriate statistics and p-values). How many drinks, on average, do WEU students drink in a typical week?
4. One of the brothers in Pi Mu Beta, a fraternity on campus said that women and men at WEU differ in their preference of lite beer. In one sentence, identify whether or not there is a difference between men and women in their preference for lite beer (be sure to provide the appropriate statistics and p-values). Who prefers lite beer more, men or women? Is the result what you expected? Why or why not?
5. The university administration believes that there is a significant difference between those who do and do not belong to a fraternity or sorority as to whether or not they drink alcohol. In one sentence, identify whether or not there is a difference between Greeks and non-Greeks (be sure to provide the appropriate statistics and p-values). What percentage of those who drink alcohol do not belong to a Greek organization?
6. Past research showed that college students, on average, rated wine coolers a 5.2 on a 1 to 7 scale where a “1” is I do not like and a “7” is I like very much. Dr. Jekyll thinks that WEU students differed from the national average in terms of their preference for wine coolers (wcooler). In one sentence, identify whether or not WEU students differ from the average college students in terms of their preference for wine coolers (be sure to provide the appropriate statistics and p-values).
7. The Director of Greek Life (and former party animal) believes that people who belong to a fraternity or sorority go out on average more nights per week than their non-Greek classmates. In one sentence, identify if there is a difference in the number of nights a student goes out on average between Greeks and non-Greeks (be sure to provide the appropriate statistics and p-values).
8. Students were asked their level of agreement or disagreement with the statements I am a party animal and I am religious. The chair of the Religion Department believes that students who state they are religious would not also say they are party animals. In one sentence, identify if the chair’s position is indeed true (be sure to provide the appropriate statistics and p-values).
9. The average WEU takes 14 credit hours per semester. The advising coordinator, Ms. Schedule, believes that there is a difference in the number of credit hours taken by an individual’s work status. In one sentence, identify whether or not this difference exists (be sure to provide the appropriate statistics and p-values). If there are any significant differences, what are they?
