54 STUDY OF AIRCRAFT BIRD-STRIKES
As worldwide air traffic volume has grown over the years, the problem of airplanes striking birds and other flying wildlife has increased dramatically
The International Journal for Traffic and Transport Engineering (Vol
3, 2013) reported on a study of aircraft bird strikes at Aminu Kano International Airport in Nigeria
During the survey period, a sample of 44 aircraft bird strikes were analyzed
The researchers found that 36 of the 44 bird strikes at the airport occurred above 100 feet
Suppose an airport air traffic controller estimates that less than 70% of aircraft bird strikes occur above 100 feet
Comment on the accuracy of this estimate
Use a 95% confidence interval to support your inference
