a. Use the data given to create a 95% confidence interval for the average number of people in a household (“number living together” is the name of the variable) for students living __on campus__. (*note- you might look at Excel question 7, pp. 270-271, for an illustration of how to do this in Excel).*

b. Interpret the confidence interval created in part a. Exactly what does it tell you?

c. Use the data to create a 95% confidence interval for the average number of people in a household (“number living together” is the name of the variable) for students living __off campus__.

d. Interpret the confidence interval created in part c. Exactly what does it tell you?

e. Compare the two confidence intervals. Is there evidence of a difference between on and off campus students in the average number of roommates?
