1. List the variables used and state the scale of measurement used for the variables listed.

• Dependent variable:
• Independent variable:
• The measurement scale of the dependent variable:
• The measurement scale of the independent variable:

1. Construct the null hypothesis and the choice/alternative hypothesis.

• Null Hypothesis (H0):
• Choice/Alternative Hypothesis (H1):

1. Who is the population in this study?
2. How many samples are involved?
3. Why was t-test chosen to solve the problem in this study??
4. Why do you need to use free sample testing?
5. Give two methods in an independent t-test that can be used
6. Based on your answer in question no (25), choose which method is appropriate to use in this study. What are the conditions for determining the option, i.e. why did you choose to use the method?
7. Write a summary of the results of the analysis according to the APA format
8. Can H0 be rejected? Why?
9. What can you conclude from the results obtained?
