You may need to use the appropriate appendix table or technology to answer this question Fewer young people are driving in year A, 64 95 of people under 20 years old who were eligible had a driver's license. Twenty years later in year that percentage had dropped to 44.7%. Suppose these results are based on a random sample of 1,500 people under 20 years old who were eligible to have a driver's license in year A and again in year (a) At 95% confidence, what is the margin of error of the number of eligible people under 20 years old who had a driver's license in year A? (Round your answer to four decimal places) At 95% confidence, what is the interval estimate of the number of eligible people under 20 years old who had a driver's license in year A? (Round your answers to four decimal places.) to (b) At 95% confidence, what is the margin of error of the number or eligible people under 20 years old who had a driver's license in year B? (Round your answer to fou decimal places.) At 95% confidence, what is the interval estimate of the number of eligible people under 20 years old who had a driver's license in year B? (Round your answers to four decimal places) to (c) Is the margin of error the same in parts (a) and (b)? Why or why not? The margin of error in part (a) is - Select than the margin of error in part (b). This is because the sample proportion of eligible people under 20 years old who had a driver's license in year B is --- Select than the sample proportion of eligible people under 20 years old who had a driver's license in year A. This leads to a --Salut interval estimate in part (b)
