1. Suppose that a survey is being planned for the purposes of estimating the average number of hours spent exercising daily by adults (18 years of age or older) living in a very large community. A list of all individuals living in the town is not available; however, a list of households is available at the office of the town clerk. a. [ ] What is the target population for this survey? b. [ ] Propose a sampling frame for this survey. State and explain what could be some of the potential defects of this frame. c. [ ] What are the elements and the sampling units of this survey? d. [ ] What would you propose as appropriate method(s) of data collection taking into account the cost and timeliness of the survey. Justify your answer. e. [] State any three potential sources of non-sampling errors that may be encountered in this survey. Explain how each of these errors could be reduced. f. [] For this study, why do you think a sample survey may be preferred to carrying out a census. (Hint: Advantages and disadvantages of sample survey and census).
