calls ("robocalls") to cell phones are not
permitted and interviews conducted by humans
are more costly.

phones affect the goal of obtaining a random
sample of voters or consumers?

selected, or the independence of the selection
of individuals?
c. which attribute of estimated consumer preference

identifi ed in (a): accuracy or precision?
