FlightStats, Inc., collects data on the number of flights scheduled and the number of flights flown at major airports throughout the United States. FlightStats data showed 56% of flights scheduled at Newark, La Guardia, and Kennedy airports were flown during a three-day snowstorm. All airlines say they always operate within set safety parameters— if conditions are too poor, they don’t fly. The following data show a sample of 600 scheduled flights during the snowstorm. Use the chi- square test with a .10 level of significance to determine whether or not flying/ not flying in a snowstorm is independent of Airliner. State the Hypotheses. What is your conclusion based on Critical-Value test? Is it any different from conclusion based on a p-value approach? Sample data follows:

Flight    American    Continental    Delta    United
Yes    70    105    95    45
No    80    55    85    65
