Among fatal plane crashes that occurred during the past 70 years, 332 were due to pilot error, 63 were due to other human error, 265 were due to weather, 290 were due to mechanical problems, and 478 were due to sabotage. Construct the relative frequency distribution. What is the most serious threat to aviation safety, and can anything be done about it? Complete the relative frequency distribution below. Cause Relative Frequency Pilot error nothing% Other human error nothing% Weather nothing% Mechanical problems nothing% Sabotage nothing% (Round to one decimal place as needed.) What is the most serious threat to aviation safety, and can anything be done about it? A. Weather is the most serious threat to aviation safety. Weather monitoring systems could be improved. B. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered. C.…
