Explanation:
This is a relationship that we use in macroeconomics.
The IS curve describes the combinations of two variables , they are interest rate and the level of income, when the market of goods and services is in equilibrium.
So, The IS curve plots the relationship between the interest rate and national income that arises in the market for goods and services
Answer: Option C
Explanation: The situation when the total demand for goods and services is unable to support the full employment level, then the unemployment arising from such a situations is called cyclical unemployment.
It is a natural phenomenon in every economy as the market forces of demand and supply operate on a very high level and are impossible to control completely.
This type of unemployment always exist in an economy to some extent due to the trends or inflation or deflation.

From the given description, Chip is using an experimental design called (A) matching.
Matching <u>is a type of experimental design where the researcher divide his or her samples into two groups of treatment conditions, which serves to ensure that before the treatment, both groups have the samples with the same characteristics, thus ensuring that the results of the experiment would not be influenced by any confounding variables that the samples have.</u>
Chip is doing this to ensure that samples that have been influenced by other variables which determine their decision to hire are distributed evenly in both the experimental and control group.
