The table shows the 2013 per capita total expenditure on health in 35 countries with the highest gross domestic product in 2013. Health expenditure per capita is the sum of public and private health expenditure (in PPP, international $) divided by population. Health expenditures include the provision of health services, family‑planning activities, nutrition activities, and emergency aid designated for health but exclude the provision of water and sanitation.

The table looks like this:

Country Dollars
Argentina 1725
Indonesia 293
Saudi Arabia 1681
Australia 4191
Iran 1414
South Africa 1121
Austria 4885
Italy 3126
Spain 2846
Belgium 4526
Japan 3741
Sweden 4244
Brazil 1454
Korea, South 2398
Switzerland 6187
Canada 4759
Malaysia 938

France 4334
Norway 6308
USA 9146
Germany 4812
Poland 1551
Venezuela 656
India 215
Russia 1587

Mean expenditure, ?1 , for all countries including the United States = $2808.66.
Mean expenditure, ?2 , when the United States is excluded = $2622.26.
The difference, ?1 - ?2 = $(2808.66 - 2622.26) = $186.39.

Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000 . To investigate such claims, one study used a special device to record the conversations of male and female university students over a four‑day period. From these recordings, the daily word count of the 20 men in the study was determined. The table contains their daily word counts. 28,408 10,084...
