Among fatal plane crashes that occurred during the past 5050 years, 699699 were due to pilot error, 8888 were due to other human error, 6060 were due to weather, 156156 were due to mechanical problems, and 164164 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
Accepted Solution
A:
Answer: Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.Step-by-step explanation:Since we have given that Number of crashes due to pilot error = 699Number of crashes due to other human error = 88Number of crashes due to mechanical problems = 156Number of crashes due to sabotage = 164Total number of crashes = 699+88+156+164 = 1167So, Relative frequency distribution :Pilot error = [tex]\dfrac{699}{1167}\times 100=59.89\%[/tex]Human error = [tex]\dfrac{88}{1167}\times 100=7.54\%[/tex]Mechanical problems = [tex]\dfrac{156}{1167}\times 100=13.36\%[/tex]Sabtoge = [tex]\dfrac{164}{1167}\times 100=14.05\%[/tex]Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
