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 = 699
Number of crashes due to other human error = 88
Number of crashes due to mechanical problems = 156
Number of crashes due to sabotage = 164
Total number of crashes = 699+88+156+164 = 1167
So, Relative frequency distribution :
Pilot error =
Human error =
Mechanical problems =
Sabtoge =
Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
