Question

The FAA Wildlife Strike Database contains records of reported wildlife strikes since 1990. Strike reporting is voluntary. Therefore, this database only represents the information received from airlines, airports, pilots, and other sources. The full dataset, consisting of 145,000 reported incidents in order of occurrence with 94 variables recorded for each, was downloaded from the FAA on 21-Jan-2014. Suppose the full dataset was used to estimate the proportion of reported wildlife strikes that involved reptiles. What is the maximum level of confidence (as a percentage... do not include the % symbol) that could be attained for this estimate?

Explanation / Answer

Sample proportion is an unbiased estimator of population proportion.

Therefore, maximum level of confidence for the proportion estimate is 99%.

(Note: to calculate exact level of confidence sample proportion is required.

to calculate sample proportion number of reported strikes that involves reptiles should be known.)
