In a city, 51 % of the population favors the incumbent, Dawn Morgan, for mayor. A simple random sample of 450 is taken. Use the normal approximation along with the continuity correction factor to find the probability that at most 230 respondents favor Dawn Morgan for mayor. Let XX be the number of respondents out of 450 that favor Dawn Morgan for mayor. Describe the distribution of XX and its parameters: ~  Select an answer χ² F T N B  ( n=n=...

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 p̂, the sample proportion, to estimate p. What is the approximate probability that p̂ 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.) [ ]

(NORMAL APPOXIMATION TO BINOMIAL) A brokerage survey reports that 27% of all individual investors have used a discount broker (one that does not charge the full commission). If a random sample of 70 individual investors is taken, approximate the probability that fewer than 21 have used a discount broker. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.
