Question

what is the answer

Suppose that a particular candidate for public office is in fact favored by 47% of all registered voters in the district. A polling organization will take a random sample of 700 voters and will use P^the sample proportion, to estimate p. What is the approximate probability that p^will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election? (Round your answer to four decimal places.) You may need to use the appropriate table in Appendix A to answer this question.

Explanation / Answer

P( Z>(0.5-0.47)/Sqrt(0.47*0.53/700))

P( Z>1.5903)

= 0.0559

So, answer is 0.0559
