USA Today presented data (Marilyn Adams and Dan Reed, “Difficult Times Battered Airlines,” September 16, 2005) to show that major airlines accounting for more than half of capacity were expected to be in bankruptcy court. The total seat capacity of major airlines was 858 billion at the time. For airlines expected to be in bankruptcy court, the following data were presented:

2004 Airline Seat Capacity (in Billions)
Airline United Delta Northwest U.S. Airways ATA Capacity 145 130 92 54 21

a. Construct a bar graph representing the contribution to the total seat capacity of the major airlines for the five airlines indicated.

b. Produce a pie chart exhibiting the percentage of the total seat capacity for the five major airlines expected to be in bankruptcy court and the combined capacity of all others.

c. Calculate the percentage of the total capacity of the airlines expected to be in bankruptcy court. Was USA Today correct in the percentage stated?
