Current FAA regulations for domestic flights generally limit pilots to eight hours of flight time during a 24-hour period. FAA administrators conduct an analysis using a large sample of flight records for domestic flights in the past year.
Let's construct a 95% confidence interval for the average flight time of pilots. There were 81 pilots in the sample.
1. What is the margin of error for the 95% confidence interval? (report to 3 decimal places)
2. What is the lower end estimate for the 95% confidence interval? (report to 2 decimal places)
3. What is the upper-end estimate for the 95% confidence interval? (report to 3 decimal places
