() * *@ (Update Return Submit 4 1 point Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 95% confidence; n = 337, x = 48 Type your answer_. 5 1 point Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. Round your final answers to 3 decimal places. A political pollster wants to know what proportion of voters are planning to vote for the incumbent candidate in an upcoming election. A poll of 100 randomly selected voters taken from more than 2000 voters in the population. Only 78 of those selected plan to vote for the incumbent candidate. Based on this sample, which of the following is a 99% confidence interval for the proportion of all voters who plan to vote for the incumbent candidate? You will need to calculate the margin of error, followed by the upper and lower end of the confidence interval. Margin of Error: choose your answer. Confidence Interval: choose your answer.
