Researchers conduct a study in which university students are asked to solve puzzles, a task that all students in the experiment report enjoying before the study. They split the students into two groups: a group that is paid money for doing the puzzles, and a group that is not. The researchers then observe how often students in each group complete puzzles during their break time when they are allowed to do whatever they want. Assuming that their results are consistent with previous findings, the researchers are most likely to find that:

"the independent variable—whether or not the students receive money for doing puzzles—has a significant effect, such that students in the paid group spend less time doing puzzles during their break time".

Explanation:

Independent variable: In psychological research, the term "independent variable is described as a variable that is being manipulated, altered or changed by an investigator or researcher in order to see or notice its effect on the dependent variable of the given study. Thus, the independent variable has a direct impact on the dependent variable.

In the question above, the research finds that "the independent variable—whether or not the students receive money for doing puzzles—has a significant effect".

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.
