Now suppose that the Delaware candidate for governor in the previous question contacts you and requests that you answer the question. You create and distribute a survey to randomly selected residents of Delaware. You get responses from 850 Republicans and 1,025 Democrats. After using your superior Excel spreadsheet skills, you determine that 13.2% of the Republicans and 11.9% of the Democrats surveyed have read the U.S. Constitution.
What is the highest confidence level for which you can claim that more Delaware Republicans have read the Constitution than Delaware Democrats?
(Enter your answer as a percentage, rounded to the nearest percent. For example, 0.535 would be 54%.)
