Problem
Life expectancy in Sweden is almost eighty years; life expectancy in India is close to sixty years. Does this prove that if an Indian moved to Sweden, he would live longer? That is, does this prove that living in Sweden causes an increase in life expectancy, or can you think of some other factors to explain these facts? What evidence might you collect to test your explanation?
