An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 130lb and 1

Vlad [161]

Answer: 0.4758

Step-by-step explanation:

Given : Mean : $\mu=137\text{ lb}$

Standard deviation : $\sigma =28.9\text{ lb}$

Also, the new population of pilots has normally distributed .

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x=130 lb .

$z=\dfrac{130-137}{28.9}=-0.2422145\approx-0.24$

For x=171lb.

$z=\dfrac{171-137}{28.9}=1.1764705\approx1.18$

The p-value = $P(-0.24$

$=0.8809999-0.4051651=0.4758348\approx0.4758348\approx0.4758$

Hence, the required probability : 0.4758
