Suppose a researcher is interested in studying differences in HIV prevalences across states. The researcher finds a report from the Centers for Disease Control and Prevention (CDC) in which the number of people with a diagnosed HIV infection in 2019 is listed for each State. Table 2 shows the numbers for some of the states in the U.S Table 2. Number of people living with a diagnosed HIV infection in 2019 in a selection of states.   State  Number of people living with a diagnosed HIV infection    Number of people in the state    District of Columbia  14,047  708,253   Florida   102,733   21,492,056   Georgia  48,625  10,628,020   North Carolina 28,629  10,501,384   South Carolina    15,622  5,157,702   Virginia 20,859 8,556,642 Source: Centers for Disease Control and Prevention.

Published May 2021. Accessed August 7, 2023.                           Based on the numbers in Table 2, the researcher concludes that HIV infections were more prevalent in South Carolina than in the District of Columbia. Is the researcher’s conclusion correct (yes/no)? (2 points) Provide an explanation in words (i.e., no calculations needed) for why you think the researcher is or is not correct (max. 4 points).

What are the two average potential outcomes (i.e., E[Y(x)] and E[Y(x*)]) that can be defined based on the research question in case 2? (max. 3 points per potential outcome). 

What would be the most appropriate study design to answer the research question in case 1? (2 points) Explain why you chose this design (2 points).

Schizophrenia is often described as having a complex, multifactorial etiology rather than a single cause. Address the following three elements related to the etiology of schizophrenia: A. Describe at least three distinct etiological risk factors or processes implicated in schizophrenia, indicating the primary type of evidence that supports each (e.g., genetic, developmental, environmental). B. Explain how these factors are thought to combine or interact, emphasizing accumulation of risk or developmental timing rather than any single deterministic pathway. C. Discuss the limits of etiological conclusions in schizophrenia research, explaining why current evidence does not justify a unitary causal model and what broader challenges this illustrates for causal inference in psychopathology.
