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 | |
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.
