The Excite Poll is an online poll at poll.excite.com. You click on an answer to become part of the sample. One poll question was "Do you prefer watching first-run movies at a movie theater or waiting until they are available on home video or pay-per-view?" A total of 8896 people responded, with 1118 saying they preferred theaters. From this survey, you should conclude that: a. a larger sample is necessary. b. Americans prefer watching movies at home. c. movie theaters should lower their prices. d. the poll uses voluntary response, so the results tell us little about the population of all adults.
