Question:

The table gives the population of the 5 largest countries in the European Union in the year 2014. Which of the following is closest to the mean population of these countries?

A 63.7 million
Explaination

To find the mean, find the total population of all 5 countries and divide by the total number of countries: 65.9 + 80.8 + 60.8 + 46.5 + 64.3 = 318.3 and 318.3 รท 5 = 63.66, which rounds to 63.7. The values in the table are given in millions, so the mean population is about 63.7 million.
