The researchers used logistic regression to predict the probability of LBW ( 1 = LWB, 0 = normal birth weight). Table 2 presents the results of the logistic regression. Interpret the overall model statistics (e.g., Pseudo R-squared, model significance) and, if appropriate, the coefficients for each predictor variable (including odds ratios, confidence intervals, and p-values). Report your results as you would in a peer-reviewed publication, such as in the results section of a manuscript (e.g., “Logistic regression revealed that…”). Briefly discuss any limitations or assumptions (e.g., regarding data quality from birth certificates). (200-300 words) Note. OR = odds ratio; CI = confidence interval. Pseudo R² = .215. Log-Likelihood = -287.87 (LL-Null = -366.92). Income is scaled per $1,000 increment. Prenatal care adequacy is ordinal (higher values indicate better care). Reference categories: smoking = no; prenatal care coded such that higher levels reflect greater adequacy.

A health services researcher is studying the distribution of systolic blood pressure (SBP) in mmHg among adults aged 40–59 in a large population-based cohort. The researcher determined that SBP in this group is approximately normally distributed with a mean (μ) = 130 mmHg and standard deviation (σ) = 15 mmHg. The provided figure shows the normal distribution of SBP. The region under the curve to the right of 145 mmHg is shaded. What proportion of adults in this population are expected to have systolic blood pressure at or above 145 mmHg? Provide the approximate probability (as a decimal or percentage) using the empirical rule (68-95-99.7 rule) or standard normal reference. Show your reasoning briefly. (2–3 sentences).

Scenario #3: Email to a Professor About a Grading Concern You received a grade much lower than expected on a major speech assignment. You know you did not do your best work on the assignment and could have tried harder, but are now worried that you won’t pass the class.  Draft an email to your professor explaining your concern and asking for help.  Write your message: Include a subject line. Use appropriate greeting, body, and sign-off. Maintain a professional tone—avoid slang, blame, or emotional language. Demonstrate principles of competent mediated communication (clarity, respect, and awareness that messages are powerful, public, and permanent)
