Given:

ABC airlines has had delays on 18 of 126 recent flights . DEF airlines has had delays 13% of the time .

Determine which airline would you expect to provide more reliable service.

Solution:

In order to determine which airline would most likely provide a more reliable service, we determine the delay percentage of ABC airlines, and compare it with the given percentage of DEF airline. To do so, we must divide 18 by 126.

= 18/126

=0.1429

Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.

= (0.1429)(100)

= 14.29%

It can be seen that the percentage delay of DEF airlines is lesser than ABC airlines, hence we can conclude that DEF has a more reliable service.

Final answer:

DEF airlines has a more reliable service sthan ABC airlin.e
