A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 13% chose chocolate pie, and the margin of error was given as +3 percentage points. Given specific sample data, which confidence interval is wider. the 95% confidence interval or the 80% confidence interval? Why is it wider? Choose the correct answer below. O A. A95% confidence interval must be wider than an 80% confidence interval because it contains 95% of the true population parameters, while the 80% confidence interval only contains 80% of the true population parameters. O B. An 80% confidence interval must be wider than a 95% confidence interval in order to be more confident that it captures the true value of the population proportion. OC. A95% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the population proportion. O D. An 80% confidence interval must be wider than a 95% confidence interval because it contains 100% - 80% = 20% of the true population parameters, while the 95% confidence interval only contains 100% - 95% = 5 the true population parameters.
