Select the best answer. suppose that 35% of the registered voters in a state are registered as republicans, 40% as democrats, and 25% as independents. a newspaper wants to select a sample of 1000 registered voters to predict the outcome of the next election. if they randomly select 350 republicans, randomly select 400 democrats, and randomly select 250 independents, did this sampling procedure result in a simple random sample of registered voters from this district?
(a) yes, because each registered voter had the same chance of being chosen.
(b) yes, because random chance was involved.
(c) no, because not all registered voters had the same chance of being chosen.
(d) no, because there were different number of registered voters selected from each party.
(e) no, because not all possible groups of 1000 registered voters had the same chance of being chosen.
