The news reports that a politician is polling at 55% of the vote versus their opponent who is polling at 45%. Can you tell the confidence level from the information given? If so, what is it? Can you tell the margin of error? If so, what is it
Homework Answers
No. C.I. is the percentage of all possible samples that can be expected to include the true population parameter. It is decided by the investigator, most commonly 95%, but any level between 0 % to 100%.
NO, We can' find the margin of error.
As Margin of Error = Critical Value X Standard Error
But, since both Critical value and Standard Error are not known, we cannot calculate the margin of error.

In a survey of 500 likely voters, 271 responded that they would vote for the incumbent and 229 responded that they would vote for the challenger. Let pp denote the fraction of all likely voters who preferred the incumbent at the time of the survey, and let p^p^ be the fraction of survey respondents who preferred the incumbent. a. Construct a 95% confidence interval for pp. Keep in mind that you should calculate the standard error making no assumptions of...

1 In the November 2016 election, Donald Trump received 49% of the votes cast in Florida (Hillary Clinton received 47%). Many news organizations conduct surveys before elections to try to predict the winner. Suppose a survey was conducted in Florida shortly before the election such that we can assume that the true proportion of the population who planned to vote for Trump was 49%. The pollsters surveyed 600 likely voters and found that 283 of them planned to vote for...

Political parties rely heavily upon polling to measure their support in the electorate. Below are the results of two polls conducted in 1996 and 1997 for four political parties. The polling organization selects people to participate in the poll using random-digit dialing and then uses some procedure to randomly select a member of the household called. Why doesn’t the polling organization just ask people in the nearest shopping center? (4 points) Compute the estimated standard error for the level of...
