Imagine that you've just read the results of a study that finds a positive correlation between gum chewing and life expectancy. which of the following would be a statistically appropriate response to the results of the study?
a. you tell all of your friends and family members not to chew gum because it is bad for their health.
b. you bemoan the possibility of living so long that you will have to chew lots of gum.
c. you purchase a life-time supply of gum because chewing gum is good for your health
d. you become curious about what third variables might cause both increases in gum chewing and increases in life expectancy.

D

Explanation:

You become curious about what third variables might cause both increases in gum chewing and increases in life expectancy.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.

no because it could make the world a terrible place to live in.
