Suppose these results ar random sample of 1,200 people under 20 years old who were eligible to have a driver's license in 1995 2016. a. At 95% confidence, what is the margin of error and the interval estimate of the number of eligible p years old who had a driver's license in 1995? Margin of error = (to four decimal places) Interval estimate = to (to four decimal places) b. At 95% confidence, what is the margin of error and the interval estimate of the number of eligible p 20 years old who had a driver's license in 2016? Margin of erTor = (to four decimal places) Interval estimate = to (to four decimal places) C. Is the margin of error the same in parts (a) and (b)?
