# Research questions using hypotheses testing in real life

a. Develop a Research Question: In your area of interest, think about a research question that could be answered using a hypothesis test. Write down this research question and explain what your research is trying to investigate.

b. State the Hypotheses: Using your research question, create the null hypothesis that will be tested and the alternative hypothesis. Be sure to use the symbols Ho for the Null hypothesis and Ha for the Alternative hypothesis.

c. One-tailed or Two-tailed: Based on your research question indicate whether you would conduct a one-tailed or two-tailed test. If you would conduct a one-tailed test indicate which direction the test would be.
