The Gallup Organization surveys adults in the United States on their views about current issues in government, politics, technology and society. A September 2017 Gallup Poll surveyed 978 U.S. adults via telephone interviews. 643 respondents reported that they believe that the federal government has too much power. The survey has a margin of error of 3.3% (0.033). Use the information above to create an interval estimate for the proportion of all U.S. adults who believe that the federal government has too much power. (a) What proportion of surveyed adults said that the federal government has too much power? Report this answer in decimal form to three decimal places. 65.746 (b) Construct a confidence interval for the population proportion that claim that the federal government has too much power. Write this interval in the form [lower value, higher value]. Start with the square brackets [,] to enter the interval answer.
