Question

Among fatal plane crashes that occurred during the past 55 ​years, 384 were due to pilot​ error, 69 were due to other human​ error, 362 were due to​ weather, 435 were due to mechanical​ problems, and 338 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?

    Answer:

    \begin{array}{ccc}{Error} & {f} & {RF} & {Pilot} & {384} & {0.242} & {Human} & {69} & {0.043} & {Weather} & {362}& {0.228}& {Mechanical} & {435}& {0.274} & {Sabotage} & {338}& {0.213} \ \end{array}

    The most serious threat is mechanical problems.

    Step-by-step explanation:

    Given

    Pilot \to 384

    Human \to 69

    Weather \to 362

    Mechanical \to 435

    Sabotage \to 338

    Solving (a): The relative frequency table

    The relative frequency (RF) is calculated as:

    RF = \frac{Frequency}{Total\ Frequency}

    Where

    Total\ Frequency = 384 + 69 + 362+ 435 +338

    Total\ Frequency = 1588

    So, the relative frequencies is as follows:

    Pilot = 384/1588 = 0.242

    Human = 69/1588 = 0.043

    Weather = 362/1588 =0.228

    Mechanical = 435/1588 = 0.274

    Sabotage = 338/1588 = 0.213

    So, the relative frequency table is:

    \begin{array}{ccc}{Error} & {f} & {RF} & {Pilot} & {384} & {0.242} & {Human} & {69} & {0.043} & {Weather} & {362}& {0.228}& {Mechanical} & {435}& {0.274} & {Sabotage} & {338}& {0.213} \ \end{array}

    Solving (b): The most serious threat

    The most serious threat is the one with the highest frequency, and that is the mechanical problems.

    Carrying out maintenance schedule and removal of potential threat are some of the ways it can be minimized.
