Geometric Mean Annual Percent Increase in International Passenger Revenues

E

There are 24 years involved. The geometric mean is = [(1 + 5100/528)^1/23]-1. In words, it is the 23rd square root of (1 + 5100/528) minus 1. So we have GM = (1

+ 9.66)^(1/23) - 1 = 0.1036 = 10.4%

To calculate the geometric mean annual percent increase in international passenger revenues, we need to determine the annual growth rate over the given time period.

The formula for the geometric mean annual percent increase is:

Growth Rate = [(Ending Value / Beginning Value) ^ (1 / Number of Years)] - 1

In this case: Beginning Value (1972): $528 million Ending Value (1995): $5,100 million Number of Years: 1995 - 1972 = 23 years

Let's plug these values into the formula:

Growth Rate = [($5,100 million / $528 million) ^ (1 / 23)] - 1

Growth Rate = [9.6591] - 1

Growth Rate = 8.6591

To convert the growth rate into a percentage, we multiply it by 100:

Growth Rate = 8.6591 * 100 = 865.91%

Therefore, the geometric mean annual percent increase in international passenger revenues is approximately 865.91%.
