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 your A7 (Round your answers to four decimal places.) (b) M 95confidence, what is the margin of error of the number of eligible people under 20 years old who had a driver's license in year B7(Round your newer to four decimal ans) 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 it? (Round your answers to four decimal aces) (c) Is the margin of error the same in parts (a) and (b) Why or why not? The margin of error in part(a) Bect 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 sin mar is Soled than the sample proportion of eligible people under 20 years old who had a driver's license in year A.
