Among fatal plane crashes that occurred during the past 6565 ​years, 613613 were due to pilot​ error, 7575 were due to other hum

an​ 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

cause...................Relative Frequency

Pilot Error............................613

Othe human error.............75

Weather...............................470

Mechanical Problems.....311

Sabotage............................342

Total: 1811

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

cause................................Relative Frequency

Pilot Error............................613/1811*100 =33.84%

Othe human error.............75/1811*100 = 4.1%

Weather...............................470/1811*100 = 25.95%

Mechanical Problems.....311/1811*100 = 17.17%

Sabotage...........................342/1811*100 = 18.88%

Total: 100%

So the relative frequency distribution is,

cause...................................Relative Frequency

Pilot Error............................33.84%

Othe human error.............4.1%

Weather..............................25.95%

Mechanical Problems.....17.17%

Sabotage...........................18.88%

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:

f(p) = 3p-2

Let p=2

f(2) = 3*2-2

Suppose the p-value is 0.1038. what is the correct interpretation of this p-value in context?
Basile [38]

The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

According to the statement

we have given that the P value and we have to find the correct interpretation of this p-value in context.

So, For this purpose, we know that the

The P - Value is the In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed.

And in the given statement ,

The given p value is 0.1038.

And this p value is a If the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

So, The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.
