A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500respondents, 14% chose chocolate pie, and the margin of error was given as ±5 percentage points. Given specificsample data, which confidence interval is wider: the 95% confidence interval or the 80% confidence interval? Whyis it wider?Choose the correct answer below.O A. An 80% confidence interval must be wider than a 95% confidence interval because it contains100% - 80% = 20% of the true population parameters, while the 95% confidence interval only contains100% - 95% = 5% of the true population parameters.B. A 95% confidence interval must be wider than an 80% confidence interval in order to be more confident thatit captures the true value of the population proportion.O C. An 80% confidence interval must be wider than a 95% confidence interval in order to be more confident thatit captures the true value of the population proportion.D. A 95% confidence interval must be wider than an 80% confidence interval because it contains 95% of thetrue population parameters, while the 80% confidence interval only contains 80% of the true populationparameters.Next
