**Poll Analysis on Handheld Cellular Phone Use While Driving**In a nationwide poll conducted in 2009, 78% (0.78) of respondents believed it should be illegal to use a handheld cellular telephone while driving a car. The poll's sample size was 900.---### Statistical Analysis Tasks**(a)** Calculate the standard error of the sample proportion. (Round your answer to six decimal places.)**(b)** Determine a 95% confidence interval estimate of the population proportion regarding the illegality of using a handheld cellular telephone while driving. (Round your answers to three decimal places.)\[ \_\_\_\_\_\_\_\ to \_\_\_\_\_\_\_\ \]**(c)** Determine a 98% confidence interval estimate of the population proportion on the same subject. (Round your answers to three decimal places.)\[ \_\_\_\_\_\_\_\ to \_\_\_\_\_\_\_\ \]**(d)** Compare the intervals calculated in parts (b) and (c). Which interval is wider—the 95% confidence interval or the 98% confidence interval?- ○ The 95% confidence interval is wider.- ○ The 98% confidence interval is wider.---**Note**: An orange button labeled "USE SALT" is present, indicating the use of a statistical learning tool for calculations.

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 ±4 percentage poits. Describe what is meant by the statement that "the margin of error was given as ±4 percentage points." (...) Choose the correct answer below. OA. The statement indicates that the study is only 4% confident that the true population percentage of people that prefer chocolate pie is exactly 13%. OB. The statement indicates that the study is 100% -4% = 96% confident that the true population percentage of people that prefer chocolate pie is 13%. OC. The statement indicates that the interval 13% ± 4% is likely to contain the true population percentage of people that prefer chocolate pie. D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 13% ± 4%.
