Question

Among fatal plane crashes that occurred during the past 70 years, 503 were due to pilot error, 90 were due to other human error, 326 were due to weather, 382 were due to mechanical problems, and 643 were due to sabotage.

What is the most serious threat to aviation safety, and can anything be done about it?

A. Sabotage is the most serious threat to aviation safety. Airport security could be increased.

B. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered.

C. Weather is the most serious threat to aviation safety. Weather monitoring systems could be improved. D. Pilot error isPilot error is the most serious threat to aviation safety. Pilots could be better trained.

Explanation / Answer

Total deaths = 503 + 90 + 326 + 382 + 643 = 1944

So the relative frequency table will be:

Since the frequency of Sabotage is highest, Sabotage is the most serious threat to aviation safety. Airport security could be increased.

Option A is correct.

Cause Calculation Relative Frequency Pilot Error 503/1944 = 0.258 or 25.8% 25.8% Other human error 90/1944 = 0.046 or 4.6% 4.6% Weather 326/1944 = 0.168 or 16.8% 16.8% Mechanical Problems 382/1944 = 0.197 or 19.7% 19.7% Sabotage 643/1944 = 0.331 or 33.1% 33.1%
