A farmer divided his piece of land into 4 equivalent groups. The quality of the soil is the same across the 4 groups of land. He planted the same crop in all 4 groups of land and recorded the yield of the crop in all 4 groups for a 4 week period. Is the study observational or experimental?

Experimental

Explanation:

Experimental study is the study in which researcher has some control over the variables where he can experiment and test over the groups. Observational study provides no control to researcher .He can only observe the process.

According to the question, study conducted by farmer is experimental as farmer has the control over quantity variable of land , grouping choice of crop etc.He is dividing  the land equally in four parts,sowing same crops into 4 groups in each piece depicts that he is testing or experimenting everything equally.

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.

the answer is       political office  

hope this .
