n airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is a

Sedbober [7]

Answer: 0.8313

Step-by-step explanation:

As per given we have,

$\mu=15.5$ $\sigma= 3.6$

Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.

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

z-score corresponds to x= 10: $z=\dfrac{10-15.5}{3.6}\approx-1.53$

z-score corresponds to x= 20: $z=\dfrac{20-15.5}{3.6}=1.25$

P-value = $P(10$

$=P(z$

Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313
