Associations Between BMI, Smoking, Sex, and Cardiovascular Health Indicators: A Statistical Analysis of Blood Pressure and Coronary Heart Disease

Read the document Inferential statistics and the document descriptive statistics.

Task  Biased on the information provided in the documents write a report on the three research questions.  

Research Questions

1. Primary Research Question Is there an association between BMI (explanatory) (continuous-ratio) systolic blood pressure (response)(continuous-ratio)?
2.  Secondary Research Question Is there an association between smoking status (explanatory) (categorical-dichotomous) and diastolic blood pressure (response)(continuous-ratio)? 
3. Secondary Research Question Is there an association between the participant sex (explanatory)(categorical-dichotomous) and prevalent coronary heart disease (response)(categorical-dichotomous)?

Your report needs to include the six sections provided below.

Introduction (~ 1 page)

1. Describe one of your research questions as the primary question of interest, clearly identifying the explanatory and response variables. 
2. Describe your two secondary research questions, identify the explanatory and response in each, and integrate them with the primary research question into a research theme.
3. Build a case for the relevance and importance of your research questions, describing what the implications might be if you find associations. 
4. Utilize at least two peer reviewed journal articles to support your claims. 

Methods (~ 1 page)

1. Describe the source of the data and how it was collected. 
2. Discuss the descriptive statistics used to examine and describe the data.
3. Discuss the statistical hypothesis tests used for each of your three research questions to examine each potential association. 
4. Describe the SAS software used to perform the analyses.

Results – Descriptive Statistics (~ 1 page)

1. Describe the characteristics of the distributions of your most important variables (primary response variable and your primary explanatory variable) individually, commenting on the distributional shape (i.e., symmetric, bell-shaped, skewed right or left).
2. Discuss the descriptive statistics for each of the variables used in your research questions and use well labeled table(s) and/or graph(s) to present these findings.

Results – Inferential Statistics (~ 1 page)

1. Describe the results of your statistical hypothesis tests for your three research questions, reporting the results, including the test statistic and p-value for each. 
2. Interpret these findings, commenting on the statistical significance and the most relevant associations found.
3. Support your text by including graph(s) and table(s) depicting these associations.

Discussion/Conclusion (~ 1 page)

1. Describe the importance and larger implications of your research, based on your interpretation of the key findings.
2. Compare your results to previous or similar studies, commenting on any unexpected findings.
3. Highlight the strengths and weaknesses of your research.
4. Comment on any unanswered questions or potential areas for further study.

Bibliography (~ 1 page)

1. Include a bibliography that cites all sources referenced throughout the report using the most current version of AMA formatting.
