The 2,000 individuals will be selected by random-digit telephone dialing and asked the question over the phone. a. What is the relevant population?
b. What is the variable of interest? Is it quantitative or qualitative?
c. What is the sample?
d. What is the inference of interest to the pollster?
e. What method of data collection is employed?
f. How likely is the sample to be representative?
