1. Suppose you would like to do a survey ofundergraduate students on your campus to find out how much time onthe average they spend studying per week. You obtain from theregistrar a list of all students currently enrolled and draw yoursample from this list.
a. What is your sampling frame?
b. What is your target population?
c. Explain how you would draw a simple random sample forthis study.
d. Assume that the registrar’s list also containsinformation about each student’s major. One could then select astratified random sample, stratifying on major. What main benefitcan result from using a stratified random sample instead of asimple random sample? Would you expect this benefit to be obtainedby stratifying on major? Explain.
e. How might you obtain a cluster sample? When shouldyou consider using this type of sampling design?
f. Which type of sampling design is most appropriate forthis research problem? Explain.
