As per given we have,
Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.
Since ,
z-score corresponds to x= 10:
z-score corresponds to x= 20:
P-value =
Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313
