2. What is your gender identity?
3. Do you live on a school campus or at home?
4. Do you drink weekly?
5. How many days a week do you drink?
I believe that the mean number of days per week that current college students between ages 1822 drink alcohol will be greater than 1.
The sampling method I used to collect my data was convenience sampling. I distributed my survey via social media (Facebook and Twitter) and text message to gather the results quickest. This way it also allowed individuals to anonymously choose if they wanted to take it or not.

Questions 1, 2, 3, and 4 all involve qualitative data. The data consists of values that can be placed into nonumerical categories. These 4 questions are measured at the nominal level because the data consists of names or labels and cannot be ranked or put into any type of order.
On the other hand, question number 5 is qantitative because it consists of values representing counts or measures. It is measured at the ratio level because the ratios and intervals of the data is meaningful and involves a true zero point.
My parameter question asked participants if they were between the ages of 1822 and attend a college or university. Out of the 34 results that I collected, 34 answered yes to this question. The proportion then is 1 or 100% of participants are between the ages of 1822 and attend a college or university. The standard deviation for my claim, or the number of days per week that students between ages 1822 who attend a college or university drink, is 1.2 and the mean is 1.9. My results show that the data I collected will be very useful because the total population of individuals who took my survey were in the category I was looking for.
I believed that the mean number of days per week that current college students between ages 1822 drink alcohol will be greater than 1. My null hypthesis is that the mean number of days per week that current college students between ages 1822 drink alcohol will be equal to 1. My alternative hypthesis would be that the mean number of days per week that current college students between ages 1822 drink alcohol will be greater than 1. I will have to conduct a righttailed test because the claim to my alternative hypothesis is greater than 1. The sample statistic for this test is 1 or 100% because 34 out of the 34 participants who took the survey answered yes to the first question. Since 34 out of 34 participants were qualified for my survey, I will use a normal distribution.
The z score is 0.1. I found this by using the equation (11.9)/(1.2(sq.root of 34)). After looking at the Pvalue chart on page 446, I foud that this give me a p value equal to .4602. z= 0.1; p=.4602. Since p>.05, I fail to reject the null hypothesis.
My claim that states the mean number of days per week that current college students between ages 1822 drink alcohol will be greater than 1 ended up being correct. My final results show that the mean number of days per week that current college students between ages 1822 drink alcohol is 2.
