Suppose that in the exit poll from the state of Florida during the year 2000 presidential elections in the United States, the pollsters recorded only the votes of the two candidates who had any chance of winning, Democrat Albert Gore and Republican George W. Bush. The polls close at 8:00 PM. The number of votes cast for the Republican in the poll is x-407. The sample size is n=765. Estimate the population proportion of republican voters with 95% confidence level. Use TWO decimal points accuracy. Select one: O a. Lower Bound 53.15% and Upper Bound 53.26% O b. Lower Bound 49.66% and Upper Bound 56.73% O c. Lower Bound 50.23% and Upper Bound 56.67% O d. Lower Bound 51.48% and Upper Bound 54.91%
