Explain the mechanism of blood pressure homeostasis. Your answer should state the name of the reflex that maintains constant blood pressure and identify all 5 components of the negative feedback loop. Also, describe in detail how the body would compensate for a rise in blood pressure, including the division of the autonomic nervous system stimulated.

In a study of red/green color blindness, 600 men and 2700 women are randomly selected and tested. Among the men, 56 have red/green color blindness. Among the women, 6 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.
(Note: Type ‘‘p_m″ for the symbol pm, for example, p_mnot=p_w for the proportions are not equal, p_m>p_w for the proportion of men with color blindness is larger, p_m<p_w, for the proportion of men, is smaller. )

To do this assignment, choose a statistical model from the list below and come up with a hypothetical study related to your research interests that could be conducted using the model. Assignment must include the following:

1. Brief background information on your topic, the research question and hypothesis.
2. State the population of interest and the sample. State the IV including levels and the DV. Be specific about what your variables are. Review “operational definitions”
3. Detail what the procedure would be for those participating in your study. Be specific about each step in the procedure.
4. Come up with a sample data set for your hypothetical study (how you think the data might look; minimum of 30 data points total). **You do not have to collect actual data** Demonstrate how the data would be analyzed using the formulas learned in class.
5. Interpret the results of the test. Relate your analysis to the question posed by your hypothetical study. NOTE: If the hypothetical data you come up with does not have significant differences, state potential reasons why there are no group differences and how a follow-up study could be conducted.

Choose from the following statistical models:

Independent t-test

Dependent t-test

One-way between-subjects ANOVA

One-way within-subjects ANOVA
