Suppose a sample of 1000 is used to estimate the fraction of voters that favor one of two candidates. If the campaign manager assumes that his candidate is ahead with a proportion 0.52 that favors the candidate.
1. What is the probability of observing a sample proportion showing that her candidate is winning?
2. If the result from sampling is a sample proportion of 0.47. How likely is an outcome like that or smaller (than 0.47), given that the true proportion is 0.52?
(Round all probabilities to four decimal places)
