The correct answer is the first one
The correct answer is 2.
Elasticity measures the sensibility of the quantity supplied or demanded when the price of the product is modified. In this example we will compute the elasticity of the supply function.
<u>The supply function is inelastic</u> in the sense than when a price increase is performed (from P1 to P2) the quantity supplied increases in a lower proportion (from Q1 to Q2). Let's prove this by calculating the percentage increase experienced by each of the two variables:
- Price: (7-4)/4 * 100% = + 75%
- Quantity supplied: (5-3)/3 * 100%= +66.66%
When there is a price increase of the 75%, the quantity supplied increases a 66.66% (<75%).

Answer:
a) combines the classical experimental design with the posttest-only control group design
Explanation:
The Solomon four group test, is a standard pretest-
posttest two group design that focuses on the posttest control design. The various combinations of
tested and untested groups have helped with the treatment and control of the groups; and have allowed researchers to ensure that confounding variables and extraneous factors haven't influenced the results. The Solomon four group design is one of the benchmarks for sociological and educational research, and combats most of the internal and external validity issues in lesser designs.
