*PART I:*

* *

*You are going to purchase a new car, but being a responsible consumer means doing a little bit of research first.*

*First, you find the vehicle you are purchasing and its price. Vehicle: Chevy Volt Price: $39,145*

*Current interest rate: 3%*

1. Using the function A(t)=P(1+rn)nt, create the function that represents your new car loan that is compounded monthly. The principle will be the price of the vehicle you selected, not how much you are putting down.

2. Being a smart financial planner, you want to figure out how many months it will be until your principal is paid down to $10,000.00. Solve for t and show all of your work. Note that *t* will be negative because the number of months will decrease the principal.

3. Lastly, you decide to keep track of your loan four times a month instead of monthly. Solve for the adjusted interest rate. Remember to use the formula A(t)=P[(1+rn)1c]cnt where c = 4. When solving for the adjusted interest rate, be sure to set it equal to 1+rn.

PART 11:

**Conduct an Observational Study**

In this assessment, you will be conducting your own survey to collect data from a sample and make inferences about the population. Think of something that interests you. It could be an important issue in the media, a hobby, or something about school. Be creative here! Feel free to contact your instructor if you have questions about any step of the process.

**Part 1**: Develop your research question. What is it that you want to know? A good research question will tell the reader exactly what your study is about and help you maintain your focus throughout the research process.

**Part 2**: Develop your survey questions. Stick to what you really want to know and be sure that your survey questions will get you the answers you need.

**Part 3**: Conduct your survey. There are many ways to gather data. You could survey people in your daily life, email your classmates (if possible), survey your friends using technology, etc.

**Part 4**: Write up your results in a report using the following format:

**Introduction** to the purpose of the study. Include your research question here.

**Methodology**: What are your survey questions and how did you collect the data?

**Results**: Put your data here in the form of a list or table.

» Include appropriate proportions or means for the data.

» Include confidence intervals for your data and what they mean in the context of your study.

**Discussion**: What conclusions can you draw from your data?
