Find the mean of these times that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight: 12 min, 8 min, 21 min, 17 min, 12 min. (Data are from Data Set 15 in Appendix B.)

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...

To find: The mean time that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight.

Answer to Problem 1CQQ

The mean time that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight is 14min.

Explanation of Solution

Given info: The data shows that the times that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight.

Calculation:

The formula for mean is,

x¯=∑xn

Mean time is,

x¯=12+8+21+17+125=705=14

Thus, the mean time that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight is 14min.
