Suppose 260 randomly selected people are surveyed to determine whether or not they took a college entrance exam. Of the 260 surveyed, 205 reported taking a college entrance exam. Identify the values needed to calculate a confidence interval at the 95% confidence level. Then find the confidence interval. z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576 Use the table of common z-scores above. Round the final answer to three decimal places.
