Among fatal plane crashes that occurred during the past 5050 years, 699699 were due to pilot error, 8888 were due to other hum

lapo4ka [179]

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 = $\dfrac{699}{1167}\times 100=59.89\%$

Human error = $\dfrac{88}{1167}\times 100=7.54\%$

Mechanical problems = $\dfrac{156}{1167}\times 100=13.36\%$

Sabtoge = $\dfrac{164}{1167}\times 100=14.05\%$

Crashes due to pilot error is the most serious threat to aviation safety as it has highest relative frequency.
