Choose the best interpretation of the slope.

A. Average Income increases 14 cents for every additional year that you live.

B. Living longer causes you to make more money.

C. Making more money causes you to live longer.

D. Average Life Expectancy increases 0.0014 years for every additional dollar of average income.

Answer 1

The slope suggests that for every additional dollar of average income, average life expectancy increases by 0.0014 years. This correlation does not necessarily imply causation, as other factors also influence life expectancy.

Step-by-step explanation:

The best interpretation of the slope in the context of the data provided is that average life expectancy increases by 0.0014 years, or approximately 0.51 days, for every additional dollar of average income. This statement implies a correlation between higher income and longer life expectancy.

However, it's important to note that this correlation does not imply causation. The data might be indicating that countries with higher average incomes might invest more in healthcare, nutrition, education, and living conditions, which could contribute to higher life expectancy. It's also worth mentioning that an individual's income doesn't directly determine their lifespan; many other factors are at play, such as genetics, lifestyle choices, and access to healthcare.
