Aresearcher wants to observe preschoolers at a local public playground to evaluate levels of cooperation. the researcher will not interact with the children or record information in such a manner that the identity of the subjects can be readily ascertained. which of the following statements is true?
a) this research would require full committee review because it involves children.
b) this research would be eligible for expedited irb review because the researcher is not interacting with the children and the playground is public.
c) this research would be eligible for exemption because the researcher is not interacting with the children and the playground is a public setting.
d) this research would be eligible for expedited irb review because the researcher is participating in the activities observed.

the correct C) This research would be eligible for exemption because the researcher is not interacting with the children and the playground is a public setting.

Explanation:

This research would not require IRB review because it would be eligible for exemption since the researcher is not interacting with the children and the playground is considered a public place.

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.

we need the diagram to answer this correctly.
