2a. State a question related to a categorical variable that can be answered using your survey data and the techniques you have studied thus far in this course. You are encouraged to develop your own question, but you may use an appropriate question from the StatCrunch website. The question you use should be about the entire population of StatCrunch U students—not just about those in the sample. Assume that your sample is representative of the population.
b. Explain the methodology you will use to answer the question you posed. Your explanation should include answers to the following questions. Do not include your analysis or answers to your question here—only describe how you will do the analysis.

• What is the variable of interest?
• What graphical techniques will you use to describe your data?
• Why are those techniques appropriate? Why did you choose them?
c. Carry out the methodology described in b above. Use StatCrunch and paste copies of the graphs/charts from StatCrunch in the space below.
d. Based on the results of b and c above, answer your question. Include an explanation of how you used the graphs and charts to formulate your answer.
