among fatal plane crashes that occurred during the past 70 years, 263 were due to pilot error, 92 were due to other human error, 573 were due to weather, 585 were due to mechanical problems, and 56 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?\ncomplete the relative - frequency distribution below\ncause\trelative frequency\npilot error\t\nother human error\t\nweather\t\nmechanical problems\t\nsabotage\t\n(round to one decimal place as needed.)
Answer
Explanation:
Step1: Calculate total number of crashes
$263 + 92+573 + 585+58=1571$
Step2: Calculate relative frequency for pilot - error
Relative frequency of pilot error = $\frac{263}{1571}\times100%\approx16.7%$
Step3: Calculate relative frequency for other human - error
Relative frequency of other human error = $\frac{92}{1571}\times100%\approx5.9%$
Step4: Calculate relative frequency for weather
Relative frequency of weather = $\frac{573}{1571}\times100%\approx36.5%$
Step5: Calculate relative frequency for mechanical problems
Relative frequency of mechanical problems = $\frac{585}{1571}\times100%\approx37.2%$
Step6: Calculate relative frequency for sabotage
Relative frequency of sabotage = $\frac{58}{1571}\times100%\approx3.7%$
Answer:
| Cause | Relative Frequency |
|---|---|
| Pilot error | 16.7% |
| Other human error | 5.9% |
| Weather | 36.5% |
| Mechanical problems | 37.2% |
| Sabotage | 3.7% |
The most serious threats to aviation safety are mechanical problems and weather, as they have the highest relative frequencies. To address mechanical problems, regular and thorough aircraft maintenance can be carried out, along with strict pre - flight and post - flight inspections. For weather - related issues, better weather forecasting systems can be developed, and pilots can be trained to handle adverse weather conditions more effectively.
