GIVEN: A researcher aims to know the impact of COVID-19 on the companies in Southwest America through interviewing the owner of different companies. The researcher wants to know the average reduction in a company's income one month after the lockdown because of COVID-19. The researcher obtained a list of registered companies through the government as well as additional information like the address and enterprise size. The researcher grouped the companies in terms of size: small, medium, and large enterprises. The researcher initially planned on randomly selecting 200 enterprises per classification. But, the researcher noticed that the cost of transportation is high because the selected enterprises in Southwest America are spread out. So, the researcher instead CHANGED the sampling design by partitioning Southwest America by cities and randomly selecting a sample of cities. Within each selected city, the researcher applied the initial plan of randomly selecting companies based on size. MULTIPLE CHOICE: Choose one correct answer. What is the variable of interest of the study? a. The average reduction of company income one month after the lockdown b. Reduction of company income one month after the lockdown c. The size of the company d. The location of the company

A researcher aims to know the impact of COVID-19 on the
companies in Southwest America through interviewing the owner of
different companies. The researcher wants to know the average

The researcher initially planned on randomly selecting 200
enterprises per classification. But, the researcher noticed that the
cost of transportation is high because the selected enterprises in
Southwest America are spread out. So, the researcher instead
CHANGED the sampling design by partitioning Southwest America
by cities and randomly selecting a sample of cities. Within each
selected city, the researcher applied the initial plan of randomly
selecting companies based on size.
MULTIPLE CHOICE:
Choose one correct answer.
What is the variable of interest of the study?
a. The average reduction of company income one
month after the lockdown
b. Reduction of company income one month after
the lockdown
c. The size of the company
