19.8 Which party does it better? An opinion poll selects adult Americans at random and asks them, “Which political party, Democratic or Republican, do you think is better able to keep the U.S. prosperous?” Explain carefully how you would assign digits from Table A to simulate the response of one person in each of the following situations.
(a) Of all adult Americans, 50% would choose the Democrats and 50% the Republicans.
(b) Of all adult Americans, 40% would choose the Democrats and 60% the Republicans.
(c) Of all adult Americans, 40% would choose the Democrats, 40% would choose the Republicans, and 20% are undecided.
(d) Of all adult Americans, 44% would choose the Democrats, 46% the Republicans, and 10% are undecided. (These were the percentages in a September 2015 Gallup Poll.)
