In a survey of 1,000 adults in a country, 652 said that they had eaten fast food at least once in the past month. Create a 95% confidence interval for the population proportion of adults who ate fast food at least once in the past month. Use a TI-83, TI-83 plus, or TI-84 calculator, rounding your answers to three decimal places.
