Question: In a study of flight attendants, salaries paid by two different airlines were randomly selected. For 40 American Airlines flight attendants, the mean is $23,870 and the standard deviation is $2960. For 35 TWA flight attendants, the mean is $22,025 and the standard deviation is $3065 (based on data from the Association of Flight Attendants). At the 0.10 level of significance, test the claim that American and TWA have the same mean salary for flight attendant.
