26. Flight Data: Use the times required to taxi out for takeoff. For American Airlines, how is it helpful to find the mean?
Taxi Out: 30 19 12 19 18 22 37 13 14 15 31 15 16 14 15 27 19 22 22 23 16 13 16 18 15 12 19 18 21 20 13 15 43 18 17 19 13 20 12 17 35 19 22 43 49 45 13 23
Airport personnel can gauge how many planes can be ready for takeoff.
To find the mean of the times required to taxi out for takeoff for American Airlines, you would add up all the values and divide by the total number of values. Here are the steps to find the mean:
1. Add up all the values: 30 + 19 + 12 + 19 + 18 + 22 + 37 + 13 + 14 + 15 + 31 + 15 + 16 + 14 + 15 + 27 + 19 + 22 + 22 + 23 + 16 + 13 + 16 + 18 + 15 + 12 + 19 + 18 + 21 + 20 + 13 + 15 + 43 + 18 + 17 + 19 + 13 + 20 + 12 + 17 + 35 + 19 + 22 + 43 + 49 + 45 + 13 + 23 = 892.
2. Count the total number of values, which is 47 in this case.
3. Divide the sum (892) by the total number of values (47): 892 / 47 = 18.98 (approximately).
Therefore, the mean of the times required to taxi out for takeoff for American Airlines is approximately 18.98.
Finding the mean is helpful in this case because it provides a single representative value for the dataset. It allows you to summarize the dataset and understand the average time taken by American Airlines planes to taxi out for takeoff. This information can be useful for various purposes, such as analyzing efficiency, comparing with other airlines, or identifying any potential areas for improvement.
