A properly conducted survey randomly selected 1,000 Canadians (from a total population of about 30 million) and 1,000 Americans (from a total population of about 300 million). Which of the following is FALSE?
A. Random selection ensures that both samples are representative of their respective populations.
B. If 2,000 Canadians and 2,000 Americans were selected for the study, we could be confident that the sample result would be more accurate.
C. A smaller proportion of the American population has been chosen. Therefore, a particular person has a smaller chance of being selected in America than in Canada.
D. A potential stratification variable for both countries could be location: eastern, middle, or western continental.
E. Random digit dialing to select people for the survey could induce biases in the results if the characteristic of interest for the survey is related to income.
