Among fatal plane crashes that occurred during the past 6565 years, 613613 were due to pilot error, 7575 were due to other human error, 470470 were due to weather, 311311 were due to mechanical problems, and 342342 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?

We have different information and we need to make a table of that, so

causeRelative Frequency

Pilot Error613

Othe human error75

Weather470

Mechanical Problems311

Sabotage342

Total: 1811

To calculate the relative distribution we need basically divide by the total and multiply for 100.

causeRelative Frequency

Pilot Error613/1811*100 =33.84%

Othe human error75/1811*100 = 4.1%

Weather470/1811*100 = 25.95%

Mechanical Problems311/1811*100 = 17.17%

Sabotage342/1811*100 = 18.88%

Total: 100%

So the relative frequency distribution is,

causeRelative Frequency

Pilot Error33.84%

Othe human error4.1%

Weather25.95%

Mechanical Problems17.17%

Sabotage18.88%

Total: 100%

The vast majority of failures are made by pilots. The best thing to do is offer them more training. Many of these problems are due to ignorance of the terrain or carelessness due to the standardized level of security that flights generally have. Lack of practice in extreme situations can cause these problems.

step-by-step explanation:

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
