For this assignment, you will review two different situations
that both involve comparing a sample to a population. Consider the
information available for each situation, choose the correct test,
and use the data to conduct it.
A researcher wants to compare the email use of the employees
at one company to the corresponding population. Data is collected
on the number of emails received by the company's employees. It
will be necessary to use this sample data, as well as population
data to determine if there is a significant difference between
both.
Population
Mean number of emails: 25
Standard deviation: 3
Sample
Mean number of emails: 20
Total employees: 100
A researcher wants to compare the number of vehicles owned by
families in one location to the larger population. Data is
collected on the number of vehicles owned by each family. It will
be necessary to use this sample data, as well as population data to
determine if there is a significant difference between them.
Population
Mean number of vehicles: 4
Sample
Mean number of vehicles: 3
Standard deviation: 1
Sample size: 100
Create a report of approximately 1-2 pages in which you
address the following:
Identify the test you selected for each situation.
Explain why it was the appropriate test.
Present the results of each test.
Explain whether or not a significant difference was found
between the sample and the population.
