Critiquing an Experimental Design
A research team wants to determine if a new teaching method causes an improvement in student test scores. They implement the new method in a classroom of 30 students for one semester. At the end of the semester, they find the class's average test score is 10% higher than the average score of the class from the previous semester. The team concludes the new teaching method caused the improvement. Based on the principles of a controlled experiment, what is the most significant flaw in their approach that undermines this causal conclusion? Explain your reasoning.

Critiquing an Experimental Design
A landowner controls a farm where a tenant farmer provides all the labor. The production possibility curve shows all technically achievable combinations of the farmer's daily leisure hours and the total bushels of wheat produced. Consider an allocation where the farmer works 10 hours a day, producing 50 bushels of wheat, but the landowner claims all 50 bushels, leaving the farmer with none. From an economic standpoint, why is this allocation considered an impossible or non-viable outcome?
Analysis of a Production Allocation
In an economic model of production, if an allocation of goods and labor is technically feasible (i.e., it lies on or within the production possibility frontier), it is always considered a practically viable outcome for the parties involved.

Viability of a Production Allocation
Evaluating Production Scenarios
A farmer works on land owned by a landowner. The table below shows the total output (in bushels of grain) based on the number of hours the farmer works per day. An 'allocation' describes the hours worked and the distribution of the resulting output. Which of the following allocations is technically possible according to the production data, but is considered an economically impossible outcome for the farmer?
Hours Worked Total Grain Produced (bushels) 0 0 4 25 8 45 10 52 12 55 Evaluating a Labor Contract Proposal
An economic model describes a farm where a laborer's work produces grain. The 'feasible frontier' represents all possible combinations of the laborer's free time and the total grain produced. Consider a point on this frontier where the laborer works 10 hours, producing 60 bushels of grain. In this specific allocation, the landowner takes all 60 bushels, leaving the laborer with none. Which statement best analyzes this allocation?
