Consider a large number of countries around the world. There is a positive correlation between a number of nintendo games per person, x and the average life expectancy, y. Does this mean that we could increase the life expectancy in Rwanda by shipping Nintendo games to that country?

a). Yes. The correlation says that as the number of nintendo games per person goes up, so does life expectancy.

b). No. If the correlation were negative, we could accept this conclusion, but the correlation is positive.

c). Yes. Positive correlation means that, when we increase x, y will also increase.

d). No. The positive correlation just shows that richer countries have both more Nintendo games per person, and higher life expectancies.

e). It makes no sense to calculate correlation between these two variables.

*I think the answer may be C, but am unsure.
