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 0.1 level of significance. Question 3 options: 1) We conclude that Airline and Status are dependent on each other, based on a p-value of 0.0012 2) We conclude that Airline and Status are not related to each other, based on a p-value of 0.0012 3) We decide that Airline and Status are independent of one another, based on a p-value of 0.9988 4) We find that Airline and Status are related to each other, based on a p-value of 0.9988 5) There are two correct answers.
