Suppose that 46.8% of registered voters nationwide support a particular candidate. An online poll is conducted to determine if his support has increased. Out of 437 likely voters who completed the poll, 272 stated that they support the candidate. a) Describe the sampling distribution model for the sample proportion by naming the model and giving the mean and standard deviation. b) Find the probability of obtaining the sample results above. Be sure to include a picture. c) Discuss your results in Part b. The candidate claims that the poll is proof that his support has increased significantly. What do you think of this claim? Do you have any concerns about this poll? Consider the conditions for the Central Limit Theorem and types of bias.
