Determine if the most appropriate statistical analysis technique is conducting a hypothesis test or constructing a confidence interval. Then, select the symbol for the corresponding parameter of interest. A large random sample of Delta flights and an Independent large random sample of united flights are to be collected. For each flight, whether or not flight time will be recorded. This data will then be used to estimate the difference in rates of flights that are on-time for Delta versus United.
