Question

Suppose the Federal Aviation Administration (FAA) would like to compare the on-time performances of different airlines on domestic, nonstop flights. The following table shows three different airlines and the frequency of flights that arrived early, on-time, and late for each. Identify the correct conclusion using the 0.01 level of significance.

Question 3 options:

1) We find that Airline and Status are independent of each other, based on a p-value of 0.1219 2) We did not find significant evidence that Airline and Status are associated with each other, based on a p-value of 0.1219 3) There is not enough information to make a conclusion. 4) We conclude that Airline and Status are related to one another, based on a p-value of 0.8781 5) We did not find significant evidence that Airline and Status are not related to one another, based on a p-value of 0.8781

Explanation / Answer

The answer is,

2) We did not find significant evidence that Airline and Status are associated with each other, based on a p-value of 0.1219.

This because p-value = 0.1219 is not less than the value of alpha = 0.01, therefore we cannot reject the null hypothesis which would have been the statement of indifference that Airline and Status are independent of each other.
