He randomly samples 30 participants at a local airport asking them what area of the U.S. they were raised (East or West): 15 are from the East and 15 are from the West.

**HELPFUL HINT: you CANNOT enter the data exactly as it is shown here. You need to do SOMETHING (involving a condition column and values) in order to set up the data for the correct t-test).

East: 1, 3, 2, 4, 2, 1, 3, 2, 1, 2, 0, 5, 3, 0, 4

West: 0, 2, 4, 4, 5, 3, 4, 4, 3, 3, 4, 5, 5, 5, 0

 

 

**HINT: when you interpret the output make sure to choose correctly if it is a one-tailed or two-tailed test based on the scenario above.
