An airport official wants to prove that p1= the proportion of delayed flights for Airline 1 was different from p2= the proportion of delayed flights for Airline 2. Two independent random samples are selected from the two airlines, each with 100 flights. To address the official's concern, a 2-sample z test was conducted and yielded a p-value 0.0124. What is the most appropriate conclusion at a 0.05 level of significance?

a) The probability that the two proportions of the delayed flights for the two airlines are equal is 0.0124, so the two proportions are unlikely to be equal.

b) The proportions of delayed flights for the two airlines are likely to be the same.

c) There is not enough evidence to conclude there is a difference between the two proportions of the delayed flights for the two airlines.

d) The proportion of delayed flights for Airline 1 is different from the proportion of delayed flights for Airline 2.
