A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 11% chose chocolate pie, and the margin of error was given as 4 percentage points. Given specific sample data, which confidence interval is wider the 90% confidence interval or the 80% confidence interval? Why is it wider? Choose the correct answer below OA. A 90% 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 OB. A 90% confidence interval must be wider than an 80% confidence interval because it contains 90% of the true population parameters, while the 80% confidence interval only contains 80% of the true population parameters OC. An 80% confidence interval must be wider than a 90% confidence interval in order to be more confident that it captures the true value of the population proportion OD. An 80% confidence interval must be wider than a 90% confidence interval because it contains 100% -80% - 20% of the true population parameters, while the 90% confidence interval only contains 100%-90% = 10% of the true population parameters

K A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 respondents, 12% 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. B OA. A 95% 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. OB. 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% of the true population parameters. OC. A 95% 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…

According to a recent random survey of 3,728 US adults, 1,939 report using their cell phones to play online games. Construct and interpret a 95% confidence interval for the proportion of US adults who use their cell phones to play online games. State: confidence interval for the true proportion of US adults who use their cell phones to play online games. Plan: ; Random: Random survey; 10%: 3,728 is less than 10% of all US adults; Large Counts: 1,939 successes and 1,789 failures ≥ 10. Do: Conclude: We are 95% confident that the interval from includes the true proportion of all US adults to play online games.

B. Identify the value of the margin of error E C. Construct the confidence interval There are 3 part to this question. Other two questions are above.
