A television news program asks viewers to log onto their website and vote on a different issue each day. The website allows visitors to select one of two choices and submit a vote. The results of the poll are reported the next day on the news program. The population to which the results of these polls can be extended is
 a. all viewers of the news program.
  b. all visitors to the website.
  c. all viewers who have voted in any of the polls.
  d. only viewers who voted in that specific poll.

Question 2

A population under study is divided into 10 smaller groups (e.g. lab sections for a large class). The opinions of the people within each group vary quite a bit, whereas the variation between the groups is not that great. Suppose you decide to take a cluster sample. However, you don't really know exactly how many people make up this population, would you still be able to take your sample?
