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.
